The concept of human resources management for the lebanese organization

Human resources (HR) are an economic category which is now very important in Lebanon. Based on realized theoretical research, we have confirmed the hypothesis that there are at least four different scientific approaches to understanding the nature and importance of human resources. The research results are a summary of definitions in the human management, description of the concept for better understanding the situation with employees in Lebanon. There are some the definition of human resources and approaches to the human resources according to some economists and economic theory schools. In microeconomic view, there are two basic approaches. In terms of business economics, the human resources are considered as the production factor. According to the managerial view, the human resources are a business resource or asset which forms part of the market value of the company and investment in HR gives additional benefits for organizations. The macroeconomic approach sees human resources as one of the production factors, respectively sources of economic growth. There is the concept of human resources management for Lebanese organizations the main idea of which is a forming a new strategy of HRM due to indicators of an effective system of human resources management and evaluation of the level of HRM in Lebanon (attraction, selection, training,assessment)

Analysis And Design Of A Modular Solar-fed Fault-tolerant Power System With Maximum Power Point Tracking

Solar power is becoming ever more popular in a variety of applications. It is particularly attractive because of its abundance, renewability, and environment friendliness. Solar powered spacecraft systems have ever-expanding loads with stringent power regulation specifications. Moreover, they require a light and compact design of their power system. These constraints make the optimization of power harvest from solar arrays a critical task. Florida Power Electronics Center (FPEC) at UCF set to develop a modular fault-tolerant power system architecture for space applications. This architecture provides a number of very attractive features including Maximum Power Point Tracking (MPPT) and uniform power stress distribution across the system. MPPT is a control technique that leads the system to operate its solar sources at the point where they provide maximum power. This point constantly moves following changes in ambient operating conditions. A digital controller is setup to locate it in real time while optimizing other operating parameters. This control scheme can increase the energy yield of the system by up to 45%, and thus significantly reduces the size and weight of the designed system. The modularity of the system makes it easy to prototype and expand. It boosts its reliability and allows on-line reconfiguration and maintenance, thus reducing down-time upon faults. This thesis targets the analysis and optimization of this architecture. A new modeling technique is introduced for MPPT in practical environments, and a novel digital power stress distribution scheme is proposed in order to properly distribute peak and thermal stress and improve reliability. A 2kW four-channel prototype of the system was built and tested. Experimental results confirm the theoretical improvements, and promise great success in the field

Libya and regional security

In theory and practice, there is a consensus that the question of regional security is becoming of great importance. This largely due to the fact that the level of international security is interlocked and heavily pending on the extent of micro-security: i.e. regional, subregional, national, local and personal. Accordingly, we will examine how Libya deals with the security issue within its regional settings. Initially, this requires throwing light on the underlying factors that heavily determine the preference and priority of which regional security arrangement to adhere. In the Libya case, there are a number of alternatives. This include: the Arab world, the Middle East, North Africa, the Arab Maghreb and the Mediterranean Region.Mesa Seguridad Internacional: La seguridad regional: estructura y coyunturaInstituto de Relaciones Internacionale

Integrated Topologies And Digital Control For Satellite Power Management And Distribution Systems

This work is focused on exploring advanced solutions for space power management and distribution (PMAD) systems. As spacecraft power requirements continue to increase, paralleled by the pressures for reducing cost and overall system weight, power electronics engineers will continue to face major redesigns of the space power systems in order to meet such challenges. Front-end PMAD systems, used to interface the solar sources and battery backup to the distribution bus, need to be designed with increased efficiency, reliability, and power density. A new family of integrated single-stage power converter structures is introduced here. This family allows the interface and control of multiple power sources and storage devices in order to optimize utilization of available resources. Employing single-stage power topologies, these converters control power flow efficiently and cost-effectively. This is achieved by modifying the operation and control strategies of isolated soft-switched half-bridge and full-bridge converters--two of the most popular two-port converter topologies. These topologies are reconfigured and utilized to realize three power processing paths. These paths simultaneously utilize the power devices, allowing increased functionality while promising reduced losses and enhanced power densities. Each of the proposed topologies is capable of performing simultaneous control of two of its three ports. Control objectives include battery or ultra-capacitor charge regulation, solar array maximum power point tracking (MPPT), and/or bus voltage regulation. Another advantage of the proposed power structure is that current engineering design concepts can be used to optimize the new topologies in a fashion similar to the mother topologies. This includes component selection and magnetic design procedures, as well as achieving soft-switching for increased efficiency at higher switching frequencies. Galvanic isolation of the load port through high-frequency transformers provides design flexibility for high step-up/step-down conversion ratios. It further allows the converters to be used as power electronics building blocks (PEBB) with outputs connected in different series/parallel combinations to meet different load requirements. Utilizing such converters promises significant savings in size, weight, and costs of the power management system as well as the devices it manages. Chapter 1 of this dissertation provides an introduction to the requirements, challenges, and trends of space PMAD. A review of existing multi-port converter technologies and digital control techniques is given in Chapter 2. Chapter 3 discusses different PMAD system architectures. It outlines the basic concepts used for PMAD integration and discusses the potential for improvement. Chapters 4 and 5 present and discuss the operation and characteristics of three different integrated multi-port converters. Chapter 6 presents improved methods for practical digital control of switching converters, which are especially useful in complex multi-objective controllers used for PMAD. This is followed by conclusions and suggested future work
