Induction machines are the most commonly used industrial drives for variety of applications. It has been estimated that induction motors consumes approximately 50 % of all the electric energy generated. Further, in the area of renewable energy sources, such as wind or bio-mass energy, induction machines have been found suitable for functioning as generators. In this context, it may be mentioned that a star-delta switching is common for the starting of three-phase induction motor. Now, it is proposed to use this star-delta switching for energy conservation of induction machines, i.e., at times of reduced loads, the machine switched back to star connection. Using a three-phase, 400 V, 50 Hz, 4-pole induction machine, it has been demonstrated that the star-delta switching of stator winding of three-phase induction machine (motor / generator operations) reconnected in star at suitable reduced loads with a switching arrangement, can result in improved efficiency and power factor, as compared to a fixed delta or star connection. The predetermined values along with the experimental results have also been presented in this report. A simulation program has been developed for the predetermination of performance of the three-phase induction machine using exact equivalent circuit. A case study on a 250 kW, 400 V, 4-pole, three-phase induction machine, operated with different load cycles, reveals the significant real and reactive power savings that could be obtained in the present proposal.

Biometrics has developed to be one of the most relevant technologies used in Information Technology (IT) security. Unimodal biometric systems have a variety of problems which decreases the performance and accuracy of these system. One way to overcome the limitations of the unimodal biometric systems is through fusion to form a multimodal biometric system. Generally, biometric fusion is defined as the use of multiple types of biometric data or ways of processing the data to improve the performance of biometric systems. This paper proposes to develop a model for fusion of the face and fingerprint biometric at the match score fusion level. The face and fingerprint unimodal in the proposed model are built using scale invariant feature transform (SIFT) algorithm and the hamming distance to measure the distance between key points. To evaluate the performance of the multimodal system the FAR and FRR of the multimodal are compared along those of the individual unimodal systems. It has been established that the multimodal has a higher accuracy of 92.5% compared to the face unimodal system at 90% while the fingerprint unimodal system is at 82.5%.

The loss of biological resources in the coastal forests of eastern Tanzania is alarming. This is due to human related activities such as vegetation clearing for agriculture and intensive livestock grazing. By their nature, these activities affect forest dependent birds through destroying habitat and or blocking migratory corridors, and thus interrupting site occupancy pattern. The aim of this study therefore, was to determine whether habitat degradation along the Tanzania’s north eastern coast affects site occupancy patterns of forest dependent birds among forest fragments and the associated savannahs. Lowland Tiny Greenbul, a forest dependent bird was used as a model. The data was collected along transects set inside the forest fragments and along the neighboring matrices. The collected data was then used to build site occupancy probability models using the software Presence. The results revealed that ideal undisturbed habitat positively influenced both the relative abundance and site occupancy probability of the model bird ― indicating the significance of maintaining habitat in their natural state for the welfare of forest dependent species and the broader biodiversity. This study emphasizes minimizing human pressures in the forests and the matrices for the persistence of the species.

Forests contribute immensely to economic and social development through formal trade in timber, environmental services, non- timber forest products, safety, net spiritual and aesthetic value. Wood is a key source of energy that has been used for millennia for cooking, boiling water, lighting and heating. Today, about 2.5billion people depend on biomass energy for cooking and heating with 87% of this energy being provided by wood. In sub-Saharan African, more than 90% of the population relies on wood fire, that is, firewood and charcoal as their primary source of domestic energy. Over 80% of urban householders and small industries use charcoal and firewood as their source of energy. Despite their numerous importance, Africa’s forest continue to decline rapidly due to increase in agricultural practices into forest lands, population growth and urbanization, increased poverty, high dependence on natural resources for subsistence and income through forest. The study centred on the implications of fuel wood demand on forest conservation in sub-Sahara Africa - a regional focus on Akure metropolitan area, Ondo State. The specific objectives of the paper were to identify firewood consumption pattern in Akure metropolitan area, and factors responsible for increased fuelwood demand in the study area. The paper adopted direct observation, oral interview and 0.05% of the study area as sample size for the study. The study observed lack of adequate alternative; poor implementation and enforcement of government regulation on forestry; poverty and poor awareness on the menace of forest depletion among others. The paper posited provision of alternative fuel with subsidy, regular awareness campaign, proper monitoring, implementation and enforcement of forest regulations with a view to achieving sustainable conservation.

in this project, we investigate the two-way satellite relaying (TWSR) system with 2 antennas at Base Stations [BSs]. The satellite used is a bend-pipe satellite which receives signals over the uplink and broadcasts these signals with some transponder gain. The signal undergoes self interference during transmission which can be overcome by having perfect knowledge of the uplink and downlink Earth Stations [ESs]. But this knowledge about the uplink and downlink ESs are difficult to produce due to reciprocity issue and transmit power limitations. So, we investigate the Channel State of Information (CSI) with Weibull Distribution and found that the design of training protocol for two-way satellite relaying is in correct state under the practical involvement of CSI estimation. We even found that both the ESs transmits orthogonal training sequence which fulfils the value of CSI for self-interference cancellation. With the help of analytically demonstrated effect of CSI estimation with Weibull Distribution over the performance of the TWSR system, we obtain reduced bit error rate and average capacity of the scheme.

Technological developments, findings, and associated improvement of structural codes together with the change in the earthquake potentials and deficiencies of the old buildings necessitate the evaluation of the present building stocks. Both the Earthquake Regulations and the Seismic Zoning Map in Turkey have been going through a fast change in the recent years. Furthermore, the fact that the structural damage due to the recent earthquakes did not change according to the regions which is indicative of the building stock with low structural quality. Kirsehir is one of these regions with low quality buliding stock. Kirsehir is a developing region in relation to the increase in population and number of buildings in recent years. Accordingly, the heights of the buildings also increase in relation to the improving economical conditions. In contrary to the older masonry buildings of 1950s, the newer buildings are manufacturing using reinforced concrete. However, the lack of control mechanisms, designs according to lower eqarthquake risks without considering the the soil- structure relationship also make the more recent buildings prone to earthquake damage. In this study, the building stock in Kirsehir and its close surroundings (constructed before 1998) was considered and grouped in relation to their floor numbers, construction methods and some other properties. The performance analyses of the considered buildings were performed by taking into account the local soil conditions and construction material. Then, the earthquake risks of these buildings are calculated.

Education can determine the formation of learners’ character, personality, and manners. Therefore, education is considered to be the most responsible for juvenile delinquency among students like brawl, drugs and free sex. Those deviances and crime indicate the low moral, manner and character of the nation. responding that phenomenon the government through the Ministry of National Education made a new effort of establishing character education model to improve the character and manner of learners. This does not mean that previously there was no character education, however today’s government emphasizes systematic character education. In this regard, teacher is the key factor of the successful implementation of character education because teacher makes direct interaction with learners. Teacher is required to prepare learning device and he then implement character education in the classroom. However, most of teachers still do not understand how to prepare Lesson Plan of character education let alone to carry it out. On the other hand, an education system that is supposed to be successful in establishing character building is the educational system in pesantren or madrasa. In principle, implanting characters is more effective through habituation and good example that is more likely pesantren or boarding school that is directly supervised by the teacher.

Vietnam's shipping fleet is in a state of surplus of small-tonnage vessels, composite cargo vessels, while there is a lack of large-scale vessels running international routes and specialized ships carrying cement, chemicals and gas. Liquefied. With such a fleet structure, the domestic fleet only accounts for 10-12% of the import and export market, of which the combined dry bulk market share accounts for 12%, containerized cargo accounts for 8%. %, liquid cargo accounts for 8%. The export market of the Vietnamese fleet is mainly China, Southeast Asia, Asia, some ships have exported to Eastern Europe but in very small quantity. Some Vietnamese ship owners have large vessels such as Container Vinalines Company, East Sea Transportation Company, Gemadept Corporation, Vietnam Shipping Joint Stock Company, have ship to Europe and North America. Most of the dry bulk carriers, mainly containerized feeder feeder ships, are used in Singapore and Hong Kong, while other major markets such as the Americas are owned by foreign shipping lines. The reason for the low market share of Vietnamese shipping is primarily due to subjective factors such as improper fleet structure; The technical condition is weak, the ship is detained many times abroad; The organization of management of service delivery of Vietnamese enterprises is weak, lack of linkage between ships, cargo owners, trade and insurance; Difficult financial resources; Weak and lack of human resources; The habit of buying CIF, selling FOB lost the opportunity to rent a means. In addition, due to some objective reasons such as the global financial crisis; Oil prices, fuel prices are unstable and continuously rising; The mechanism of government policy is lacking and incomplete.

The raw materials of secondary catalytic processes must be pre-refined. Among these refining processes are the deasphalting and demetallization including their thermo adsorption (or thermo-contact adsorption) variety. In oil processing four main processes of thermo-adsorption refining of hydrocarbon residues are used: ART (Asphalt Residual Treating - residues deasphaltizing), 3D (Discriminatory Destructive Distillation), developed in the US, ACT (Adsorption-Contact Treatment) and ETCC (Express Thermo-Contact Cracking), developed in Russia. ART and ACT are processes with absorbers of lift type reactor, while 3D and ETCC processes are with an adsorbing reactor having ultra-short contact time of the raw material with the adsorbent. In all these processes, refining of hydrocarbon residues is achieved by partial Thermo-destructive transformations of hydrocarbons and hetero-atomic compounds with simultaneous adsorption of the formed, on the surface of the adsorbents, resins, asphaltene and carboids, as well as metal-, sulphur - and nitro-organic compounds. Demetallized and deasphalted light and heavy gas oils or their mixtures are a quality raw material for secondary deepening refining processes (catalytic and hydrogenation cracking, etc.), since they are characterized by low coking ability and low content of organometallic compounds that lead to irreversible deactivation of the catalysts of these deepening processes.

Ensuring safe and easy operation, providing relative uniform dose in the product and maximizing radiation utilization are the basic design principles for each Co60 industrial irradiator to maintain radiation safety. The study shows an assessment for four industrial irradiators to determine which active results were been maintained by using basic design principles. Different designs elements of the chosen irradiators have been illustrated and studied. The study shows that IRASM and ROBO industrial irradiators satisfy all basic design principles. IAEA-NR3772 irradiator maintains only two of the three basic design principles due to rotating door. Brevion irradiator satisfies only the principle of relative uniform radiation dose in product. Without affecting radiation safety, this study proposes a new design of the irradiator to maximize energy utilization by adding a new track for low density products and also a static irradiation for cultural heritage beside the main track of high density products.

This work investigates the compressive strength of bamboo panels made from the locally grown bamboos in Osun State of Nigeria. There are five different species of bamboo grown in Nigeria but the specie commonly found in the Southwest of Nigeria in large quantity is Bambusa Vulgaris. Despite its versatility in the construction of low cost houses, little is made use of it other than as scaffolds and shoring of concreting of slabs in building. As structural elements such as reinforcement, it s use is non-existent despite its high tensile strength in excess of 400MPa stronger than mild steel as reported by Xiaobing (2007). Although, bamboo is not as good in compression but this is only ascertained for some variants of bamboos in the Asia but such is not available for the species grown in the Southwest of Nigeria. The current work focuses on the compressive capacity of short panels with and without reinforcements. It is interesting that bamboo panels of various dimensions of 350mm, 300mm, 250mm and 200mm in height and constant width of 200mm exhibited compressive strength decreasing with reduction in slenderness ratio. The average compressive strength ranges from 14MPa to 19.67MPa for 200mm panel and from 18.1 MPa to 22.56MPa for 350mm panel. With improved infill, the panel strength improves considerably with over 40% for the stockiest type and about 25% increase for the slender panels.

This paper presents development and implementation of a real-time, vision-based landing system for VTOL UAV. We use vision for precise target detection and recognition. A UAV is equipped with the onboard raspberry pi camera to take images and raspberry pi platform to operate the image processing techniques. Today image processing is used for various applications, in this paper it is used for landing target extraction. And vision system is also used for take-off and landing function in VTOL UAV. Our landing target design is used as the helipad ‘’H’’ shape. Firstly, the image is captured to detect the target by the onboard camera. Next, the capture image is operated in the onboard processor. Finally, the alert sound signal is sent to the remote control (RC) for landing VTOL UAV. The information obtained from vision system is used to navigate a safe landing. The experimental results from real tests are presented.

In this paper, microcontroller based sinusoidal pulse width modulation (SPWM) single-phase inverter is emphasized to constant frequency conversion scheme for wind power application. The wind-power generator output voltage and frequency are fluctuated due to the variation of wind velocity. Therefore, the AC output voltage of wind-generator is converted into DC voltage by using rectifier circuit and this DC voltage is converted back to AC voltage by using inverter circuit. SPWM technique is used in inverter to get nearly sine wave and reduce harmonic content. The rating of inverter is 500W, single-phase, 220V, 50 Hz. The required SPWM timing pulses for the inverter are generated from the PIC16F877A microcontroller. Circuit simulation was done by using Proteus (7 Professional) and MATLAB(R 2008) software. The software for microcontroller is implemented by using MPASM assembler.

This study sought to identify psychological challenges affecting primary school orphans in Wanganui Community in Zimbabwe. The study employed a mixed method approach combining questionnaires with teachers and care givers, interview sessions with orphans and in-depth interviews with community social/development worker. The study finds that lack of love, lack of attention and withdrawal were the main signs and symptoms of psychological challenge in the community. The study revealed that the term and symptoms of psychological challenges were understood differently between African context and Western context. The study recommended that action must be taken as soon as possible once the signs and symptoms which include lack of love, lack of attention to rectify the psychological challenges faced by the community.

This paper investigate the effects of superiors’ performance evaluation behaviors on subordinates’ work-related attitudes mediated used performance measure. We used leadership style initiating structure and consideration and performance measure use (objective and subjective measures) on managerial work related attitudes (goal clarity and evaluation fairness). We test our hypotheses using survey data from 56 middle-level managers in 4 services organizations. The results from Structural Equation Model with PLS show that an initiating structure leadership style has significant effect goal clarity and used objective performance measure mediated relationship initiating structure and goal clarity and used subjective performance measure not mediated relationship consideration leadership style and fairness in evaluation. Consideration leadership behavior instead only has a direct impact on fairness in evaluation. These findings have important implications for management accounting research on superiors’ use of performance measures, and provide an explanation of some of the problematic findings in the literature.

Bank failures threaten the economic system as a whole. Therefore, predicting bank nancial fail- ures is crucial to prevent and/or lessen its neg- ative e ects on the economic system. Financial crises, a ecting both emerging markets and ad- vanced countries over the centuries, have severe economic consequences, but they can be hard to prevent and predict, Identifying nancial crises causes remains both science and art, said Sti- jn Claessens, assistant director of the Interna- tional Monetary Fund. While it would be bet- ter to mitigate risks, nancial crises will recur, often in waves and better crisis management is therefore important. Analyses of recurrent caus- es suggest that to prevent crises, governments should consider reforms in many underlying ar- eas. That includes developing prudent scal and monetary policies, better regulating the nancial sector, including reducing the problem of too- big-to-fail banks, and developing e ective macro- prudential policies. Despite new regulations and better supervision, crises are likely to recur, in part because they can re ect deeper problems related to income inequality, the political econo- my and common human behavior. As such, im- provements in crisis management are also need- ed. This is originally a classi cation problem to categorize banks as healthy or non-healthy ones. This study aims to apply Discriminant analysis and Support Vector Machines methods to the bank failure prediction problem in a Sudanese case, and to present a comprehensive compu- tational comparison of the classi cation perfor- mances of the techniques tested. Eleven nancial and non- nancial ratios with six feature groups including capital adequacy, asset quality, Earn- ing, and liquidity (CAMELS) are selected as pre- dictor variables in the study. Credit risk also been evaluated using logistic analysis to study the e ect of Islamic nance modes, sectors and payment types used by Sudanese banks with re- gard to their possibilities of failure. Experimen- tal results are evaluated using accuracy of pre- diction. Features selection has shown that new groups can be identi ed from CAMELS ratios 1 and narrowing the data set space to 11 factors instead of eighteen. Discriminant analysis has i- denti ed 3 ratios with highest predictive power which are: EAS (Ratio of equity capital to total asset) , LADF (Ratio of liquid assets to deposits and short term funds) and RFR(Rain Fall Ra- tio) , the later ratio is a novel one used for the rst time by this research.
