Expatriation in Malaysia: Predictors of Cross-Cultural Adjustment among Hotel Expatriates

The stress experienced by expatriates is usually caused by the inability to adjust to the host culture, which largely results from their lack of social skills needed in dealing with the new cultural environment. Thus, the main purpose of this study is to identify the predictors of cross-cultural adjustment among expatriates in Malaysia, by focusing on expatriates in hotel industry. The findings from the study could help clarify the over generalization made of data which are usually based on certain locations and groups of expatriates. Two hundred and three expatriates participated in the study. Personality, language ability, previous international experience, training, human resource support, social support, culture distance and family adjustment were analyzed using the multiple regression analysis to determine the predictors of adjustment. The data, which was drawn from a drop and collect method, self-administered questionnaire, revealed that social support and family adjustment were the most influential predictors of hotel expatriate adjustment. The findings also suggest that over generalizations of findings across disciplines are rather inappropriate. Detail discussions on the methods, findings, limitations, and suggestions for future research are presented in the paper.

Multifeature Biometric Based Authentication System

Authentication a system by biometrics is one of the systematic way of identifying a person without any spoofing. Multifeature biometric palm vein authentication is in the progression of being endlessly refined and developed. Multispectral palm vein biometric system has its applications over many areas which includes the access control, hospitals, bank and also in application of forensic. An individual's palm vein image is converted into data points by algorithms, which is then compressed, encrypted, and stored by the software. Whenever a person access it, the data is compared with the stored one and thus verification is done. This work proposes a multi feature palm vein recognition method where the features of the input images are extracted with the efficient methodologies like Spatio local binary pattern, which is the advanced technology of LPB and modified radon transform. Once after the features are extracted they are classified. This classification is done using Support Vector Machine (SVM) algorithm. The proposed method effectively accommodates the rotational, potential deformations and translational changes by encoding the orientation conserving features. The proposed system examines multifeature biometric based authentication system using a setup where the images are said to be contactless. These databases were obtained from CASIA and IIT Delhi. The results obtained are said to be effecient than any other results obtained using different methodologies in earlier papers discussed in the literature survey.
LOCATING TUMOR IN MRI BRAIN IMAGE BASED ON CLASSIFICATION AND 3D RECONSTRUCTION

Brain tumour is the most dangerous disease to cure which occurs when abnormal cells grows in the brain. In this paper, we proposed a methodology to analyse the brain images and 3D reconstruction of MRI images. Initially, the redundant tissues and noises are purged from the input image by means of the skull stripping approach. Then, segmentation using FCM is applied on the skull stripped image. After that the firstorder statistical attributes and the co-occurrence matrix are calculated from the segmented image. These extorted attributes are then inputted to the K-NN classifier to categorize the normal and the anomalous MRI brain images. Ultimately, the images categorized as anomalous then undergoes 3D reconstruction process by means of the depth map estimation so as to position the tumour precisely.
Incidence of Dysphotopsia in Patients Implanted with the C-flex® Intraocular Lens with 360° Enhanced Edge: A Questionnaire-Based Study

Background: To evaluate the incidence of dysphotopsia associated with the hydrophilic C-flex® monofocal intraocular lens (IOL) with 360° enhanced edge in patients undergoing cataract surgery. Design: Single-centre (hospital), consecutive case study Participants: Forty patients (average age, 76.6 years [range, 62-85 years]) without co-morbidity who underwent phacoemulsification surgery. Methods: All patients were implanted with the hydrophilic C-flex® (570C) monofocal IOL (Rayner Intraocular Lenses Limited, Hove, UK) through a 2.8 mm incision. The C-flex® has 360° enhanced edge designed to reduce the centripetal migration of the lens epithelial cells. Patients underwent a slit lamp examination 1 day, 1 week, 1 month and 3 months postoperative, and were asked to complete a questionnaire describing any visual symptoms at their one-month or three-month visit. Main outcome measures: Incidence of dysphotopsia and patient satisfaction. Results: Eighteen (45%) patients reported no ocular symptoms at their 1 or 3 month postoperative visit, and none of the 22 (55%) patients who did report visual disturbances found their symptoms debilitating. The most common post-operative visual phenomenon was glare, reported by 23% of patients; unwanted imagery was noted in 17% (7) patients. Almost all patients (98%) patients stated that they were either very satisfied or satisfied with their visual outcomes following C-flex® lens implantation. Conclusion: The C-flex® IOL was associated with a low incidence of dysphotopsia and a high degree of satisfaction with postoperative visual outcomes. Unwanted imagery, which could be related to the lens implant, occurred in only one out of forty patients.

Factors to enter the study involve the age range of 15-49, affliction with PCO, satisfaction of taking part in a study and the factors for leaving it including being affected with galactorrhoea (i.e. automatic lactation from breasts), thyroid problems, Cushing syndrome or the consumers of corticosteroid drugs. The data were analyzed by means of SPSS software and the descriptive statistics tests and regression. The results of descriptive statistics tests indicated that the average age of 26.28± 5.59 years, body mass index (BMI) of 28.09 ± 5.06, %5.5 of the participants are illiterate, %17.8 of them are people with less than high school diploma, %24.7 have high school diploma degree, and %52.1 of them have university degrees. The average score for the quality of life among women was 111.36 ± 21.39 as well. The greatest factor influencing the quality of life according to the achieved score in these patients were menstruation problems, hirsutism, emotional problems, weight, and finally infertility respectively. By means of regression test there was a meaningful statistical correlation with significance level value of (p<0.05) between the quality of life with BMI, number of pregnancy, intervals between menstruation cycles, and the extent of satisfaction with body image. Polycystic ovary syndrome has a negative impact on the patients' quality of life. The symptoms of PCOs may be affecting the patients due to their perceptions, values and culture.
An Adaptive Energy Efficient Packet Forwarding Method for Wireless Sensor Networks

: In Wireless Sensor Network (WSN), Sensor nodes have limited processing capabilities, therefore simplified protocol architecture should be designed to make communications simple and efficient. Due to this limited power supply, every solution elaborated for these networks should be aimed at minimizing the energy consumption. In previous approach, the original data packets are split into a number of sub-packets equal to the number of disjoint paths from source to destination. This approach is applied sequentially in that network which takes more computational time. The proposed approach splits the original messages into several packets such that each node in the network will forward only small sub-packets. The splitting procedure is achieved by applying the Chinese Remainder Theorem (CRT) algorithm. This approach is applied in entire network which takes low computational time. The objective is to improve the energy in wireless sensor network.

Expanding the Applications of Picosecond Lasers

Picosecond laser technology has garnered much interest since arriving on the dermatological scene. While its effectiveness in removing tattoos has been well documented, demonstrating its use in other skin lesions is an ongoing process. Because quality switched nanosecond lasers and picosecond lasers share a similar mechanism, clinicians hope that picosecond lasers will prove to be useful for similar skin lesions. There has been a great focus in particular on proving its effectiveness in treating pigmented lesions, acne scarring, photodamage, and wrinkling. The early data and impressive safety profile of picosecond lasers suggest that clinicians may have another tool they can use to treat these troublesome skin conditions particularly in patients with darker skin types. picosecond lasers. While these early studies are limited by patient numbers, the results have been promising and the safety profile is maintained in all skin types.

Performance Analysis of Space-Time Trellis Coding (STTC) based on Maximal Ratio Combining and Equal Gain Combining diversity Techniques

: In this paper, we use the maximal ratio combining (MRC) diversity and equal gain combining (EGC) diversity to evaluate the performance of space time trellis coding (STTC). Different diversity techniques are available for the analysis of space time codes. This paper presents the two diversity techniques to measure the performance of the space time trellis codes Bit error rate (BER) and signal to noise ratio (SNR) are the control parameters used to analysis the performance of the maximal ratio combining diversity and equal gain combining diversity with Rayleigh fading Channel. Simulation result shows that the bit error rate versus EbNo is presented in presence of the maximal ratio combining diversity and equal gain combining diversity in Rayleigh channel. The result reveals that the wireless communication system has better performance when space time trellis coding (STTC) technique is used for receive diversity.
Survey Paper of Fuzzy Data Mining using Genetic Algorithm for Intrusion Detection

— In spite of of growing information technology widely, security has remained one challenging area for computers and networks. Recently many researchers have focused on intrusion detection system based on data mining techniques as an efficient strategy. Intrusion Detection is one of the important and essential area of research. This work has explored the possibility of integrating the fuzzy logic with Data Mining methods using Genetic Algorithms for intrusion detection. Due to the use of fuzzy logic, the proposed system can deal with mixed type of attributes and also avoid the sharp boundary problem as the reasons for introducing fuzzy logic is two fold, the first being the involvement of many quantitative features where there is no separation between normal operations and anomalies. Thus fuzzy association rules can be mined to find the abstract correlation among different security features rather than to extract all the rules meeting the criteria which are useful for misuse detection. Genetic algorithm is used to extract many rules which are required for anomaly detection systems. So, proposed architecture for Intrusion Detection methods by using Data Mining algorithms to mine fuzzy association rules by extracting the best possible rules using Genetic Algorithms.
Mitigation of Fault Current using Parallel- Resonance Type FCL

Fault Current Limiter (FCL) provides low cost solutions to replace conventional protection devices. This protects other equipment on the system from getting damaged by excessive fault currents.FCL became best option to reduce ratings of circuit breakers and may limit the electromagnetic stress in associated equipments. The considered structure prevents voltage sag and phase-angle jump at Point of Common Coupling (PCC) after occurrence of fault. This Project considers a new parallel-LCresonance type fault current limiter (FCL) that uses a resistor in series with a capacitor. The considered FCL is capable of limiting the fault current magnitude near to the pre-fault magnitude of distribution feeder current by placing the resistor in the structure of the FCL. In this way, the voltage of the point of common coupling does not experience considerable sag during the fault. In addition, the considered FCL does not use a superconducting inductor which has high manufacturing cost. The performance of implemented FCL is evaluated in the presence of several faults. The simulation results reveal the applicability of FCL. The simulation results are obtained using MATLAB/Simulink software.
Effects of Nigella sativa Oil and Thymoquinone on Renal Oxidative Stress and Apoptosis Rate in Streptozotocin-Diabetic Rats

The effects of Nigella sativa oil (NSO) and thymoquinone (TQ) on diabetes, renal oxidative stress, lipid peroxidation and apoptosis rate were investigated in streptozotocin (STZ)-diabetic rats. Forty five Sprague Dawley rats were randomly distributed into 5 groups (n=9): healthy control; diabetic control; diabetic given NSO (1ml/kg); diabetic given TQ (3 mg/kg) and diabetic co-administered with NSO and TQ, orally for 4 weeks. Diabetes was induced by a dose of STZ (50 mg/kg, i.p.) in fasted rats. Blood samples were collected for biochemical analysis. Kidneys were removed for determination of tissue antioxidant capacity, lipid peroxidation and apoptosis rate. The results showed that oral co-administration of NSO and TQ significantly increased serum insulin and decreased serum levels of glucose, glycosylated hemoglobin (HbA1c), urea, creatinine and alkaline phosphatase in diabetic treated rats. Treatment with NSO and TQ significantly increased activities of antioxidant enzymes (SOD, GPx and CAT), increased serum level of reduced glutathione (GSH) and decreased lipid peroxidation and apoptosis index. In conclusion, NSO and TQ exhibit good antidiabetic and antioxidant effects; improve renal function and reduce both malondialdehyde (MDA) and apoptosis rate in diabetic rats. Therefore, NSO and TQ may be beneficial for diabetes mellitus associated with nephropathy due to oxidative stress. [Dalia A. Hafez.

PWM Dimming Control for High Brightness LED Based Automotive Lighting Applications

Received Jan 18, 2016 Revised Apr 4, 2017 Accepted Jun 11, 2017 In recent years, the use of high brightness LEDs has become increasingly accepted as light sources in mainstream vehicles. However, LEDs are semiconductor devices having electrical characteristics completely different to the traditional lamps. The output luminous flux of an LED is determined by the forward current running through it. Therefore they cannot be powered directly from the automotive battery using the conventional driving techniques. They require specialized driving systems which can ensure the optimal flow of current through LEDs, while maintaining the required level of output luminous. This paper discusses the importance of luminous control for LED based lamps. A design example of boost type DC-DC switching converter with pulse width modulated (PWM) dimming control is presented. In the end, simulation has been presented using MATLAB/Simulink simulation package to ensure the system’s performance within the desired parameters
