Abstract

In this growing market of smart phones, Android is an open source platform of Google that has become one of the most popular operating system. As a result, protecting applications running on Android becomes of interest. Currently, Reverse engineering of Android applications is much easier than on other architectures, due to the high level but simple byte code language used. Hence, the goal is to minimize and manage risks of software flaws. Anti-Reverse engineering techniques can be used to prevent reverse engineering. This paper discusses the possible code obfuscation techniques and process exploitation techniques on the android platform. Our approach aims at increasing the complexity of the control flow of the application so that it becomes tough for a reverse engineer to get the business logic performed by an android application.

Abstract

Tourism encompasses economic activities viz. accommodation, transportation, food and beverage, information dissemination and entertainments etc. This sector generates a large investment and financing opportunities. As per the estimate of the World Tourism Organisation, India is projected to become the world's fifth largest business travel destination. Indian tourism sector is expected to get USD 109.30 billion investment by 2020. The growth of tourism is heavily depended upon the availability and accessibility of financial resources over above the geographic attributes for tourist attractions. West Bengal, a state of India has a great scope to be the destination of tourism due to well developed communication links&strategic location ; above all its diversified and rich tourism resources such as mountains, sea, jungle, mangrove area, religious sites, heritage, culture, fairs and festivals. Developing tourism and attracting tourists need substantial financing investment. Tourism projects require large initial investment and then tourism business organisations/tourism entrepreneurs need funds for staring entreprises. This paper is an attempt to analyse and understand empirically the financial aspects of the tourism industry of West Bengal. The present study is based on both primary and secondary data. The scope of tourism investment and financing at different nodes of tourism development across West Bengal have been identified on the basis of published reports by the Central Government, the State Government and private institutions. Primary data on financial perspective have been gathered through a survey on selected tourism business organisations/tourism entrepreneurs located in West Bengal to understand their views and opinions regarding tourism in West Bengal. Findings of this paper related to problems and prospects of the financial aspects of tourism shall help to formulate strategy for tourism development in West Bengal at desired level.

Abstract

The conventional method of VSWR measurement using Vector Network Analyzer (VNA) is carried out in the Laboratory by using known impedance calibration standards such as Open-Short-Mismatch terminations. The measurement uncertainty of the calibrated VNA system is directly proportional to the uncertainty of the known quantities of these standards. The mismatch terminations were calibrated at NPL. The uncertainty of Open and Short is also required to be considered for estimating the uncertainty of VNA. The in house facility is made use for developing the procedure to carry out the calibration for Open and Short terminations. This paper gives the practical method of implementation of calibration of Open-Short terminations by establishing traceability and uncertainty factors.
