Multilateral comparisons in the ICOP project:issues, methods and empirical results

This paper examines the feasibility of constructing a consistent set of multilateral comparisons of manufacturing sector output and productivity within the framework of the ICOP project. A major objective of the paper is to construct truly multilateral comparisons using the existing data base of the ICOP project. This data base consists of data constructed essentially on the basis of detailed bilateral comparisons. Multilateral unit value ratios are built up from the lowest level possible (the product level). The second objective of the paper is to examine in-depth the problem of aggregation of unit value ratios. Various aggregation methods, both well-known methods and new ones, are applied and sensitivity of the results is examined. New multilateral aggregation methods are developed which take into account differences in number of matches of the underlying binary comparisons, as well as the Laspeyres-Paasche spread which is considered to be a general indicator of reliability. Finally, the paper presents empirical results derived from the application of the above procedures to data for eight countries for the 1987 benchmark year

Bivalve fishery of Bhimili Estuary, Visakhapatnam, Andhra Pradesh

The Bhimili Estuary situated in Visakhapatnam District of Andhra Pradesh is a fairly large but shallow estuary and supports the livelihood of over 5000 fishers. Nearly 3000 clam/oyster pickers exploit the bivalve resources of this estuary. Finfishes like Mugil cephalus and Caranx sp., shrimps such as Metapenaeus monoceros, Fenneropenaeus indicus, Penaeus monodon and the crab Scylla serrata are the major species contributing to the fishery of this estuary. The Gostani River joins the sea at Bhimilipatnam carrying freshwater from Anantagiri hills, Padmanabhan, Boni, Pandrangi, Taditorru, Gudivada, Chittivalasa,Jutmill,Mulakuddu and Nagamayyapalem. Clams and oysters are distributed up to a stretch of 5-6 km from Bhimili municipality office point. The clam/oyster fishing grounds are Moolakuddu, Magamayyapalem, Thotepalem, Chinnanagarama, Asipalem and Gudivada

128-bit Vectorization on Cha-Cha20 Algorithm for Device-to-Device Communication

In 5G networks, device to device(D2D) communication is the advanced technology, and it has the major advantages when compared with traditional systems. The coverage area of the system increases by device-to-device transmission which renders with low latency. No doubt, for the upcoming technologies D2D communications is an added advantage but in various views this kind of transmission is still under risk. D2D communication is transferring the information from one device to another device without the involvement of base station. So, the communication is possible with less delay time. Attackers are possible into the D2D communications. To provide the security in communication, encryption algorithms are used. The main theme of the Encryption algorithms is it should execute with less delay time to provide faster communication and in particular CHA-CHA20 offers the secure communication for encrypting the data packets to securing the data. Vectorization on Cha-Cha20 Algorithm provides the security with less delay time compared to AES encryption Algorithm and Cha-Cha20 algorithm. Compared to other encryption algorithms in cryptography, Cha-Cha20 is suited for resource constrained devices

Cephalopod fishery of Visakhapatnam - trend and present status

Andhra Pradesh contributes nearly 8% to the total marine fish production of India. The cephalopods contribute a little over 1% to the total marine fish landings of Andhra Pradesh. In Andhra Pradesh, cephalopods are landed by large trawlers (12-14 m, 98/110 HP), known as sona boats and smaller trawlers (9.5-10 m, 68/90 HP). Total cephalopods landed during the period 2000-2010 was 23629 t and the total effort was 37399153. Cephalopod production increased from 1011 t in 2000 to over 2300 t in 2002. Thereafter there was a declining trend up to 2006. In 2006-2007, the production increased to over 2500 t. In 2008, there was a drastic decline. However, there has been an increasing trend in production in 2009-2010 (Fig. 1). Cephalopods contributed 0.53% in 2000 and 1.6% in 2010, to the total marine fish landings of Andhra Pradesh (Fig. 1). The annual average cephalopod production for the period was 2148 t, forming an average 1.04% of the total marine fish landings in Andhra Pradesh

Prawn (Penaeus monodon) seed exploited along the coast of Visakhapatnam and Vizianagaram districts of east coast of Andhra Pradesh

The prawn business proved the best among all the businesses because of its profit earned on investment and high value in export trade. The demand for prawns is increasing day by day. Many prawn and acquaculture farms have come up in Visakhapatnam and Vizianagaram districts of Andhra Pradesh. To meet the demand the fishermen folk started exploitation of prawn seed from the surf zone

On the strike bt seafood exporters at Visakhapatnam fisheries harbour in Andhra Pradesh

Visakhapatnam Fisheries Harbour Is one of the major fisheries harbours in India. Every day about 275 to 300 small mechanised boats, 150 to 175 Sona boats and 150 to 200 Mini and Mexican trawlers go out for fishing from this harbour. About 300 to 350 fish traders including local fisherwomen depend completely on this fish business for their livelihood. Each trader gets atleast Rs. 200/- per day
