Improvement in productivity can only be achieved by means of Systematic analyses and optimization of production processes in welding. Capable Production processes and ergonomic interventions may provide the basis for the Manufacture of welded products of consistently with high quality and productivity. This can be approached by determining the process parameters, proper outcomes measures, outcomes comparison with the goals, collecting new improvement suggestions, then make applications and provide progress by continuous assessment by questioning and other forms.Keywords

A sensor is a miniature component which gauge physical parameters from the environment. A sensor measures the physical parameters and transmits them either by wired or wireless means. In wireless medium the sensor and its allied components are called as node. A wireless sensor node is self-assured by a processor, local memory, sensors, radio, battery and a base station accountable for receiving and processing data collected by the nodes. The incorporation of multiple types of sensors such as seismic, acoustic, optical, etc., in a single network platform and the evaluation of the overall coverage of the system also presents numerous interesting challenges. The sensor-based military applications involves intrusion detection, perimeter monitoring, information gathering and smart logistics support in an unknown deployed area, sensor-based personal health monitoring, location detection with sensor network and movement detection using wireless sensor network. This paper gives a detailed description about the impact of clustering mechanism in dense wireless sensor network.Keywords

This paper introduces an design of next generation auto theft prevention system. As vehicles become more sophisticated, vehicle security systems must be stronger than ever before. A modern vehicle utilizes remote keyless entry system and immobilizer system as the main weaponry against vehicle theft. Project proposed here aims to design a next generation auto theft prevention system by adding significant enhancements and modernizing the existing system and thus try to overcome the drawbacks. There is a long list of features implemented in this project smart gravitational lock, cryptographic keyless entry, touch screen ignition, etc., The features are implemented with the help of 3-axis MEMS Accelerometer, 3-axis MEMS Magnetometer, IEEE 802.15.4 wireless networking protocol, TFT display, GPS Receiver, GSM cellular modem.Keywords

Friction welding can be used to join different types of ferrous metals and non-ferrous metals that cannot be welded by traditional fusion welding processes. The process parameters such as rotational speed, friction pressure, forging pressure, friction time and forging time play the major roles in determining the strength of the joints. In this investigation, an attempt was made to develop empirical relationships to predict the tensile strength and interface hardness of friction welded dissimilar joints of AIS I304 austenitic stainless steel (ASS) and AA6082 aluminium (Al) alloy using statistical tools such as design of experiments, analysis of variance and regression analysis. The developed empirical relationships can be effectively used to predict tensile strength and interface hardness of friction welded dissimilar joints of ASS-AI at 95% confidence level.

Introduction: Physical inactivity has various harmful effects but in case of chronic diseases patients perceive various barriers for physical activity. This study aims to find such barriers in Chronic Kidney Disease patients.
Methodology: This is an observational study conducted in dialysis unit of a tertiary care hospital with 104 both female & male patients of age group 40–60 years undergoing hemodialysis (HD) at least for past 6 months. Patients with recent MI, stroke & with physical impairment were excluded. Consented patients participated .Human Activity Profile Questionnaire (HAP) was used to assess the patient’s physical activity level and patient related perceived barriers for physical activity .
Result: Among 104 patients, male-female ratio was 62:42, mean age was54.56 years, mean dialysis vintage was 27.85 months (range 6-120 months). Hypertension (91.3%), Diabetes (53.8%) were most frequent chronic co-morbidities. According to MAS and AAS of HAP, 55.8%, 43.3%, 1% patients were respectively impaired, moderately active & active. The most frequently reported barriers were fatigue or tiredness (54.8%), shortness of breath (51.9%) (p 0.03), fear of getting hurt (22.1%), body pain (21.2%). Other reported barriers are joint pain, family protection, lower limb swelling, foot ulcer, chest pain, less self confidence, anxiety, overstressed, depression. Shortness of breath is the most influential barrier and statistically significant (p0.04).
Conclusion: There were a number of patient related perceived barriers for physical activity were identified and among that fatigue & SOB were found to be influential factors.

Background: Extensor tendon attrition in Rheumatoid arthritis is very common and if not treated properly, can lead to substantial loss of hand function. Here we present the rehabilitation of a 45 years female patient following extensor tendon reconstruction in zone 5.
Materials and Method: The motor assessment included examination of active range of motion, grip and pinch strength and hand function was done during first visit and at the end of 3rd week, 6th week and 12th week. The patient received physiotherapy (immobilization method) and the program was divided into three phases.
Results: The test results were used to find the efficacy of immobilisation method, author’s modification of the program and home based exercises. There was 60 to 80 percentile of ROM improvement in wrist joint, 50 to 90 percentile of ROM improvement in digits .By comparing 6th week and 12th week DASH there was about 47% improvement in upper limb functional activities The results show that the management combined with a comprehensive rehabilitation programme and commitment on the part of the patient makes it possible to achieve satisfactory treatment out comes enabling a return to normal daily functioning
Conclusion: The functional recovery achieved indicates the advisability of using immobilisation method in post-operative rehabilitation of patients with extensor tendon injury.
