A Review paper on Friction stir Welding process parameters
Friction Stir Welding (FSW) was invented by Wayne Thomas at TWI (The Welding Institute), and the first patent applications were filed in the UK in December 1991. Initially, the process was regarded as a “laboratory” curiosity, but it soon became clear that FSW offers numerous benefits in the fabrication of aluminum products. Friction Stir Welding (FSW) has become a major joining process in the aerospace, railway and shipbuilding industries especially in the fabrication of aluminum alloys. The process uses a spinning non-consumable tool to generate frictional heat in the workpiece. Worldwide, there are now over 135 licensees of FSW and new techniques and applications are being developed daily. This paper looks at the review, on friction stir welding process, various welding variables like tool rotation, transverse speed, tool tilt, plunge depth and tool design, for the welding of aluminum alloys or various dissimilar alloys. Applications, future aspects, and several key problems are also described.

Machining Challenges in Stainless Steel – A Review
In today’s world, AISI Stainless Steel contributes to almost half of the world’s production and consumption for industrial purposes. Stainless Steel is most popular alloy widely used in part manufacturing due to its inherent properties like high strength, great corrosion resistant, high ductility etc. but are hard materials to machining on-base performance criteria like metallurgical aspect, low thermal conductivity, chip formation, cutting tool wear and surface integrity. The surface roughness and material removal rate have been identified as quality attributes and are assumed to be directly related to performance, productivity, and production costs. In this paper study of various machining problem discussed by different researchers and their probable solution, which helps to reduce tool wear, increase corrosion resistance, high surface finish by reducing machining complexity.

Implementation of Hybrid Data Collection (Mobile Element and Hierarchical Clustering) in WSN
Wireless sensor network considers as real-time embedded system deployed in a particular region to sense various types of environmental parameters such as temperature, pressure, gas, humidity etc. The huge applications of WSN like habitat monitoring, forest fire detection, surveillance, transport monitoring etc. have created a lot of interest among the researcher community in recent past. Typically, WSNs are densely deployed in hazardous places where battery recharge or replacement is nearly impossible and human monitoring scheme is highly risky. There are many typical issues such as power constraints, limited computing capacity, open environment; radio connectivity makes the sensor nodes faulty many times. Once the network is established, nodes keep on sensing the information and the battery power goes exponentially. Whenever the nodes detect any event, they send the information to the other nodes or to the base station. Sometimes it happens that the same information received by nearby sensor nodes can be received by the base station that makes the network inefficient. To avoid this data redundancy and to make the network most energy efficient, data aggregation and sensor fusion have been emphasized in the literature. Many routing protocols with many different ideas have been proposed in the literature to make the network energy efficient. A cluster-based routing protocol is one of these efficient ideas, where sensor nodes are divided into a number of groups and each group is called as a cluster. One group leader is elected in each cluster known as Cluster Head (CH). Data aggregation is obtained at the leader node. The leader node/CH is only responsible for sending the message to the BS. The general system model for clustering based WSN. LEACH is the first famous hierarchical routing protocol which is proven to be most efficient over traditional routing protocol. In LEACH, the CH is elected in a probabilistic manner and tries to balance the load at each sensor node on a rotation basis. In the proposed model, an attempt has been made to improve the performance of LEACH protocol in view of electing an appropriate Super Cluster Head (SCH) among the CHs by applying suitable fuzzy descriptors. Only SCH is allowed to send the message to the BS by reducing the number of message retransmissions performed by the CHs.

Comparison of FxLMS and NFxLMS Algorithms in MATLAB Using Active Vibration Control
The paper presents simulation results of the performance of adaptive filtering algorithms such as Filtered –x Least Mean Square (FxLMS) and the Normalized Filtered-x Least Mean Square (NFxLMS) algorithm using the concept of active vibration control. The FxLMS and NFxLMS algorithms are most popular in adaptive filtering feed-forward control methods. The FxLMS and the NFxLMS are used in order to overcome the disadvantages of conventional Least Mean Square (LMS) algorithm. The MATLAB implementations for both the algorithms are carried out and the parameters such as convergence rate, efficiency, and step size results are compared using the principle of Active Vibration Control.

Manilkara zapota (L.) P.Royen (Sapodilla): A Review
Manilkara zapota, also known as Sapodilla, is very commonly distributed in the Indian subcontinent. It is an important member of Sapotaceae family as it is well known all over the world for its traditional medicinal uses. Numerous phytoconstituents have been reported from the plant by different authors that are responsible for many biological effects such as anti-inflammatory, anti-arthritis, anti-bacterial, anti-fungal, anti-oxidant, anti-tumor and anti-diabetic activities. The present article describes a detailed review of literature for this plant species including taxonomy, pharmacology, and phytochemistry in an organized way. This review paper will surely serve as an important source for the future scientific investigations on this plant.
