The application of finite-difference time-domain (FDTD) numerical modeling and Hilbert transformation for the image enhancement and detection of buried engineering utilities using surface ground-penetrating radar (GPR) technique is demonstrated in a typical sedimentary terrain of Lagos Nigeria. Accurate delineation and precise location of such subsurface features is of effective use for engineering and environmental studies. A traverse magnetic (TM-) mode formulation was adopted for the models; and perfectly matched layer (PML) absorbing boundaries were implemented for wave absorption at the modeling grid edges. Four synthetic models were developed; three single-layer models of a single pipe buried at depth (z) of 2m, two pipes 10m apart and concrete bars buried at z=1.5m, and one double-layered model of multiple pipes buried at z=1.5m. The electrical properties of the models are; single-layered earth-system (vadose zone): ?_r=9, ?=1mS/m ; pipes: ?_r=12, ?=1mS/m, bars: ?_r=16, ?=1mS/m. The two-layered subsurface, had a thin-layer of air-earth interface of ?_r=1 and ?=0, upper layer of vadose zone sediment and lower-layer (saturated zone) of ?_r=25 and ?=5mS/m. The µ was set equal to its free space value, µ_0 for all the materials. The 2D GPR data acquired in some parts of Southwestern Nigeria and processed using basic functions such as dewow, filtering and application of gains. The resulting GPR radargrams were subjected to advanced attribute analysis using Hilbert transformation (HF) in order to establish the suitability of HF for GPR signal image enhancement that would aid the interpretation of the location of the buried utilities. The model investigations revealed that the electrical and the magnetic properties of the medium hosting the buried utilities, and the depth of burial plays a major role in controlling the image resolution obtained in a sedimentary terrain. The results from the field data are in general agreement with the numerical FDTD modeling experiments.

The metal taking capacity of several types of biomass, agro products and by-products has gained attention during recent years. In the present study, one such material i.e., coconut shell powder was chosen as the biosorbent for the removal of Cu(II) from aqueous solutions. The adsorption capacity of this sorbent was investigated by batch experiments. High adsorption (>90 %) is achieved in the present study.

Organizational culture is defined as an assembly of traditions, values, procedures, conceptions and attitudes which creates the context of activities in the organization. The purpose of this study is to examine the influence of organizational culture on employee job performance. The study sought to determine the influence of organizational culture on employee performance at Kenya Ports Authority. Specifically it sought to determine the influence of competitive culture, entrepreneurial culture, bureaucratic culture and consensual culture on employee performance at Kenya Ports Authority. A descriptive research design was adopted to carry out the study. The target population for the study was 106 employees working for KPA and the sampling frame was a list of employees obtained from the human resource management department. The study utilized simple random sampling technique to draw a sample of 43 employees from the population under study and used a questionnaire as a tool for data collection. Descriptive statistics measures such as mean and standard deviation were used to analyse the data, while inferential statistics, and particularly regression analysis was used to draw inferences about the population under study. During the study, data was analysed using Statistical Package for Social Sciences (SPSS) version 22 as a tool and analysed data was presented using tables, graphs and charts. Thirty six usable responses were received and analysed. The findings reveal that organizational culture has an influence on employee performance. Competitive culture had a greater influence on employee performance from the four types of culture analysed. The study recommends that management comes up with sound organizational policies that creates enabling environment for employees to exhibit a culture that enhances employee performance.

This study, entitled "Investigating the Effect of Emotional Intelligence on the success of business in marketing" was conducted with an overall objective and 5 sub-objectives in the Bou Ali industrial estate of Hamedan in 2013. This research is a descriptive-analytic study in the form of a causal - comparative survey. The research population is 180 individuals and includes all the managers and persons in charge in the manufacturing and service factories in Bu Ali industrial estate. The sample size was estimated at 123 by Cochran's formula and it was randomly selected. Data were analyzed through three questionnaires. One standardized Sybrya shrink EQ questionnaire with 33 questions and emotional intelligence two self-report questionnaires for marketing intelligence and marketing success, collecting using SPSS software version 19 and by multivariate regression. Face and content validity of three questionnaires were estimated and then assessed by Cronbach's alpha coefficient, which in all questionnaires was 70/0. Results showed that emotional intelligence had effect on the success of marketers and marketing firms. Accurate results suggest that the two self-awareness and self-control factors significantly correlate with the success of marketers and persons in charge of marketing firms. The other three factors of self-motivation, social awareness and social skills have no significant correlation with the variable of success of marketers and persons in charge of marketing firms. Also, between the two factors of self-awareness and self-control, self-control factor is more effective than the other.

One of the main issues that marketing managers are faced with it is decisions about the distribution of goods. Decisions about the structure of the distribution channel are important in at least in two dimensions. First, the decision has a direct effect on other marketing strategic planning decisions (including pricing policy, advertising, packaging, etc). Second, decisions regarding distribution channels require long-term commitment. It takes several years to be deployed a desired distribution system and can’t be changed easily. Distribution means delivering the product to the consumer at the right time and place. In marketing Association of America's definition distribution channel is the structure of the organizational units within the company and outside the company, brokers, wholesalers and retailers that market goods or services. Distribution channels always include the manufacturer and the final consumer, the main duty of distribution system is that place goods to potential customers in the right time and place. Today managers becoming more important due to the distribution issue, according to the distribution, physical distribution and management of it and the cost and interaction between analysis, planning, and control of service levels are physical tasks of distribution management. Companies achieve competitive advantages using distributed systems.

The Sivatattvaratnakara, a Sanskrit work of Basavaraja, the ruler of a small ruling Keladi dynasty. In this work he discussed variety of sciences in which the Ayurveda system of medicine is most important one. He deals the subject in the 21st and 22nd Parts of the work. It has been a practice in India to trace the origin of arts, sciences etc., to superior gods and it is believed that Ayurveda also was created for the welfare of mankind by the Supreme Being Brahman. In this work we find a condensed form of the legend related to the origin of Ayurveda. Here Basavaraj gives detail account on the different diseases and healing methods. He was a scholar-king deals with a vast number of subjects in general and particularly all branches of science like Ayurveda (medicine), chemistry, toxicology, typology, weapons, metallurgy, horticulture, child care and sacraments, geography, astronomy, cosmography, astrology etc.

Corona effect has been considered as a source of substantial loss particular to High Voltage AC Transmission lines. The project report presents comprehensive account of development of a Matlab Simulink based model for the Corona Effect which is designed considering Peek’s equation. The model provides analysis of Corona loss impact on Transmission power in response to the variation in the factors on which Corona effect depends upon. The transmission power has been simulated to plot Corona losses based on variation in Temperature, Conductor Radius and Conductor spacing.

The aim of the paper is to produce faster results when pipelining above the inner most loop. The concept of outerloop pipelining is tested here with Fast Fourier Transform. Reduction in the number of cycles spent flushing and filling the pipeline and the potential for data reuse is another advantage in the outerloop pipelining. In this work we extend and adapt the existing SSP approach to better suit the generation of schedules for hardware, specifically FPGAs. We also introduce a search scheme to find the shortest schedule available within the pipelining framework to maximize the gains in pipelining above the innermost loop. The hardware compilers apply loop pipelining to increase the parallelism achieved, but pipelining is restricted to the only innermost level in nested loop. In this work we extend and adapt an existing outer loop pipelining approach known as Single Dimension Software Pipelining to generate schedules for FPGA hardware coprocessors. Each loop level in nine test loops is pipelined and the schedules are implemented in VHDL. Across the nine test loops we achieve acceleration over the innermost loop solution of up to 7 times, with a mean speedup of 3.2 times. The results suggest that inclusion of outer loop pipelining in future hardware compilers may be worthwhile as it can allow significantly improved results to be achieved at the cost of a small increase in compile time.
