Foreign direct investment and economic growth: empirical evidence from India

Abstract: Foreign direct investment (FDI) inflows are considered to be one of the key factors in determining economic growth. As a fast developing economy, India has attracted lot of FDI in the recent past. The country which enjoys a higher economic growth is in a great position to attract larger FDI as it has the ability to generate higher return on the foreign investments. The study discusses the relationship between FDI flows into the country and economic growth during the period January 2000 to December 2014 using the quarterly data. The purpose of the study is to find the interrelationship between FDI and gross domestic product (GDP) in India. The study uses correlation, Granger causality test, Johansen cointegration test and vector autoregression (VAR) for studying the interrelationship between the variables. This study explores a positive association between the FDI inflows and GDP in the Indian economy. The study explores the unidirectional relationship flowing from FDI to GDP.

Design of a communication aid for physically challenged

Abstract: Communications between deaf-mute and a normal person have always been a challenging task. This paper describes a way to reduce barrier of communication by developing an assistive device for deaf-mute persons. The advancement in embedded systems, provides a space to design and develop a sign language translator system to assist the dumb people, there exist a number of assistant tools. The main objective is to develop a real time embedded device for physically challenged to aid their communication in effective means. The proposed work in this paper is to implement a system without handheld gloves and sensors and by capturing the gestures continously and converting them to voice and vice versa, thus making the communication simpler for deaf and dumb people by a handheld embedded device along with the hardware setup. The effectiveness of the work is verified under MATLAB environment and further in future dedicated voice output will be produced corresponding to the text and the gesture images captured.

Novel tri-band series fed microstrip antenna array for THz MIMO communications

Abstract: A novel tri-band series fed microstrip two-element array antenna is reported in this paper for Terahertz (THz) multiple-input multiple-output (MIMO) communications. Each series-fed array consists of four radiating sections constructed using graphene material. The radiating sections consist of a square loop loaded with a diamond-shaped radiator to offer multi-frequency operation. The proposed antenna operates at 2.3 THz, 3.2 THz and 4.5 THz. The antenna offers an effective 10 dB reflection coefficient bandwidth of 38 GHz, 43 GHz and 60 GHz centred at 2.3 THz, 3.2 THz and 4.5 THz respectively. The isolation enhancement between the antenna elements is achieved using a serpentine resonator. The port-to-port isolation is greater than 15 dB in all the operating bands. The realized antenna gain is greater than 5 dBi in all the operating frequencies. The MIMO metrics of the proposed two-element antenna array is estimated and the results are presented. The envelope correlation coefficient (ECC) is less than 0.2, the diversity gain is close to the theoretical limit of 10 dB and the mean effective gain is close to unity.
