Issues faced by hotel human resource managers in Alexandria, Egypt

This study investigates challenges faced by human resource (HR) managers and their practices to cope in hotels of Alexandria city, Egypt. The researcher undertook semi-structured interviews with HR managers in four- and five-star hotels in Alexandria. The study findings revealed several themes related to HR challenges faced by HR managers in the process of recruitment, selection, training, turnover and retention. Fortunately, customs and traditions have become limited in adversely affecting work in hospitality, except for married women. The coping practices adopted by HR managers are discussed. The study implications are put forward to HR managers to overcome the HR challenges in the hotel industry, such as conducting a cooperation protocol between hotels and academic institutions, developing educational hotels with faculties, institutions and hotel schools, or signing cooperation protocols with neighbouring hotels. By improving employment conditions and rewards, the negative trends can be reversed. Finally, the paper acknowledges research limitations and makes suggestions for future research, such as other hospitality sectors, hotel grades, geographical areas, and the whole of Egypt.Keywords: Alexandria, hotels, human resource management, qualitative researc

Feature Representation for Online Signature Verification

Biometrics systems have been used in a wide range of applications and have improved people authentication. Signature verification is one of the most common biometric methods with techniques that employ various specifications of a signature. Recently, deep learning has achieved great success in many fields, such as image, sounds and text processing. In this paper, deep learning method has been used for feature extraction and feature selection.Comment: 10 pages, 10 figures, Submitted to IEEE Transactions on Information Forensics and Securit

Performance comparison of conventional synchronous reluctance machines and PM-assisted types with combined star-delta winding

This paper compares four prototype Synchronous Reluctance Motors (SynRMs) having an identical geometry of iron lamination stacks in the stator and rotor. Two different stator winding layouts are employed: a conventional three-phase star connection and a combined star-delta winding. In addition, two rotors are considered: a conventional rotor without magnets and a rotor with ferrite magnets. The performance of the four SynRMs is evaluated using a two-dimensional (2D) Finite Element Model (FEM). For the same copper volume and current, the combined star-delta-connected stator with Permanent Magnets (PMs) in the rotor corresponds to an approximately 22% increase in the output torque at rated current and speed compared to the conventional machine. This improvement is mainly thanks to adding ferrite PMs in the rotor as well as to the improved winding factor of the combined star-delta winding. The torque gain increases up to 150% for low current. Moreover, the rated efficiency is 93.60% compared to 92.10% for the conventional machine. On the other hand, the impact on the power factor and losses of SynRM when using the star-delta windings instead of the star windings is merely negligible. The theoretical results are experimentally validated using four identical prototype machines with identical lamination stacks but different rotors and winding layouts

Performance evaluation of synchronous reluctance motors with and without permanent magnets

Nowadays, a growing interest in the efficiency and the cost of electrical machines has been noticed. Therefore, Synchronous Reluctance Motors (SynRMs) have become more attractive, thanks to their higher efficiency and nevertheless acceptable cost compared to induction machines. The rotor design of SynRMs with or without permanent magnets (PMs) has a huge effect on the motor efficiency, torque density and power factor. This paper introduces an evaluation for the performance of SynRMs with and without PMs in terms of efficiency, torque and power factor maps. Three different rotor designs for the same machine have been compared. For one machine, the experimental measurements have been obtained and the validation of the simulation results have been confirme
