Abstract:Radio Frequency Identification (RFID) is essentially a wireless method of identification of physically placed objects in a certain state space. It is the most emerging technology these days which is becoming the alternate for barcode. Hence this technology is receiving lot of attention comparatively over past few years. RFID technology is used to automatically identify any item or a package. Automatic identification can be done with the help of RFID Tags and RFID Reader units. An RFID tag contains the transponder that can transmit wireless information over short distance. This information is then received by the device called RFID Reader and further processed through middleware infrastructure. Billions of RFID tags are successfully installed worldwide. Tons of RFID Applications are being developed in the various fields like Healthcare, Engineering, Agri-food, Live-stocks etc. for traceability purpose. Familiarization with the benefit and the risk of RFID is important before using this technology. The shadow of this technology has made a huge impact on our daily lives. This text gives the brief review of RFID Technology with discussion on frequency ranges, standards, and applications with emerging innovations.
Keywords: RFID, Smart Tags, RFID Reader, Transponder, Antenna, Middleware, Traceability.

Abstract:This paper presents a system for recognizing static hand gestures of alphabet in Bangla Sign Language (BSL). A BSL finger spelling and an alphabet gesture recognition system was designed with Artificial Neural Network (ANN) and constructed in order to translate the BSL alphabet into the corresponding printed Bangla letters. The proposed ANN is trained with features of sign alphabet using feed-forward backpropagation learning algorithm. Logarithmic sigmoid (logsig) function is chosen as transfer function. This ANN model demonstrated a good recognition performance with the mean square error values in this training function. This recognition system does not use any gloves or visual marking systems. This system only requires the images of the bare hand for the recognition. The Simulation results show that this system is able to recognize 36 selected letters of BSL alphabet with an average accuracy of 80.902%.
Keywords: Artificial Neural Network, Back-propagation Neural Network, Bangla Sign Language, Gestures Recognition, Sign language Recognition.

Abstract:Cloud computing is a set of IT services that are provided to a customer over a network on a leased basis and with the ability to scale up or down their service requirements. Usually Cloud Computing services are delivered by a third party provider who owns the infrastructure.Cloud Computing holds the potential to eliminate the requirements for setting up of high-cost computing infrastructure for IT-based solutions and services that theindustry uses. It promises to provide a flexible IT architecture, accessible through internet from lightweight portable devices.This would allow multi-fold increase in the capacity and capabilities of the existing and new software.This new economic model for computing has found fertile ground and is attracting massive global investment. Many industries, such as banking, healthcare and education are moving towards the cloud due to the efficiency of services provided by the pay-per-use pattern based on the resources such as processing power used, transactions carried out, bandwidth consumed, data transferred, or storage space occupied etc.In a cloud computing environment, the entire data resides over a set of networked resources, enabling the data to be accessed through virtual machines.
