Abstract

The journal subscription data of the Central Library (CL) at the Indian Institute of Technology (IIT), Kharagpur during 1995‐97 is analysed to assess the prevalent information drought experienced by researchers in less developed countries. The rationale of the study, some of the myths about electronic alternatives over print media, etc. are explained. A study conducted in 1995 at the CL by gathering subscription details from other IITs to explore the options of resource sharing is extracted to present the duplication rates of costly journals. Quantification of research publications from the IIT, Kaharagpur and India are also attempted using electronic databases like CCOD and INSPEC. The budgeting pattern of CL is presented from the IIT’s Annual Report. Some possible suggestions to get over the information drought are also explored.

Abstract

This paper deals with standardising commands for CD‐ROM searching, such as NISO Z 39.58 and ISO 8777, and the command languages evolved through EasyNet and Euronet. The standard commands are also compared with the software from database providers SilverPlatter, Dialog, and ISI. Apart from a discussion on the various attempts towards standardising search software, the groundwork for command languages and their implementation, the influence of the command languages on the evolving CD products is also highlighted.

Abstract

Purpose

This paper aims to highlight the research output of library and information science of the BRICS (Brazil, Russia, India, China and South Africa) nations during the ten year period, i.e. 2005-2014, as reflected through the Web of Science database.

Design/methodology/approach

This study used Social Science Index (SSCI) of Web of Science (WoS) citation database to collect data for the ten year period. All records indexed in SSCI were refined by subject area of “Information Science and Library Science” and selected countries. The downloaded results were analyzed by using specific parameters.

Findings

WoS indexes different kinds of documents, such as articles, conference proceedings, biographical items, book reviews, corrections, editorial material, letters, reprints and reviews. Out of the BRICS output, almost 90 per cent of papers were articles. Other types of documents included conference papers, review papers and book reviews. China contributed nearly half of the documents followed by Brazil, South Africa, India and Russia. On an average, a document had cited 34 references. More than one-third of records did not receive any citations. It has been observed that the titles that had 11-16 words attracted the most number of citations. The top ten publishers in whose journals the researchers published included Emerald, Elsevier and Springer. The primary subject areas were information science and library science, information systems, interdisciplinary applications and management. About 85 per cent of the documents were published in English. Around 93 per cent of the non-English research publications were in Portuguese, the official language of Brazil.

Originality/value

There are not many studies on BRICS countries and that too about Library and Information Science (LIS) research output. This study may reveal insights into how LIS researchers interact with local and global issues in a specific spectrum of the world community.

Abstract

Purpose

The purpose of this paper is to describe the development of a personalised information support system to help faculty members to search various portals and e‐resources without typing the search terms in different interfaces and to obtain results re‐ordered without human intervention.

Design/methodology/approach

After a careful survey of various tools and techniques available for computerised client‐centred information services, the study selected to apply web usage mining, proxy level data collection and a vector space retrieval model to develop the personalised information support for teaching and research in a higher education institution.

Findings

There are practical constraints in the implementation stage. There is considerable difficulty in getting real and correct user interests and mapping them effectively into the products and services offered by the library. Also the interests of users change continuously. If multiple users share the same PC, it is difficult to identify the user as there is no one‐to‐one mapping between user and IP address.

Research limitations/implications

The paper has not considered cases for all the faculty members due to time constraints. The results obtained from the system also need correlation with the sources actually used by the faculty to test its efficacy in a highly fluid research situation like higher academics.

Practical implications

A pragmatic client‐centred information support prototype described in this paper may find use in other institutions needing similar information support.

Originality/value

This paper demonstrates the pragmatic application of ICT for linking users and e‐resources in an academic library.

Abstract

Purpose

The paper aims to assess the level of preparedness of the Central Libraries of the Indian Institutes of Technology (IITs) to personalize content and seeks to determine whether the personalization service prototype being developed at IIT Kharagpur can be extrapolated to the remaining IITs.

Design/methodology/approach

A questionnaire was sent to the Librarians of the seven IITs, designed to compare the available information resources and services, with special emphasis on user interests and personalization aspects. The survey was supplemented by study visits to a couple of the Institutes.

Findings

Kharagpur and Mumbai have implemented personalization services in some form while the remaining IITs plan to adopt them in the near future. There is also a strong case for extending Kharagpur's personalization service, currently in project mode, to the other IITs.

Research limitations/implications

IIT Madras and IIT Kanpur failed to return the questionnaires, so relevant information regarding these Institutes had to be collected from their web sites and other available sources. There is also scope for further research to accurately access the current status of personalization activities in all the IITs.

Practical implications

With parallel interests and similar research and information facilities, personalization services in one IIT can be replicated and utilized by all the others, leading to greatly enhanced library services in all the Institutes.

Originality/value

This one of a kind survey underlines the need for and possibility of making content personalization a reality in advanced technical libraries. The results obtained are valuable to all IIT libraries in particular and academic/technical libraries in general.

The purpose of this paper is to apply asymptotic waveform evaluation (AWE) to the transient analysis of a two‐layered counter‐flow microchannel heat sink.

Abstract

Purpose

The purpose of this paper is to apply asymptotic waveform evaluation (AWE) to the transient analysis of a two‐layered counter‐flow microchannel heat sink.

Design/methodology/approach

A two‐layered counter‐flow microchannel heat sink in both steady state and transient conditions is analysed. Finite element analysis is used in the steady state analysis whereas AWE is used in the transient analysis.

Findings

A two‐layered microchannel produces different temperature distribution compared to that obtained for a single‐layered microchannel. The maximum temperature occurs at the middle of the bottom wall whereas the maximum temperature of a single‐layered microchannel is at the outlet of the bottom wall. The time taken to reach steady state is also investigated for different coolant flow rate and heat flux boundary conditions. It is observed that when fluid velocity increases, the time taken to reach steady state decreases, however, when the heat flux increases, the time taken to reach steady state does not change.

Research limitations/implications

The fluid is incompressible and does not undergo phase change. The use of AWE provides an alternative method in solving heat transfer problem.

Practical implications

New and additional data will be useful in the design of a microchannel heat sink for the purpose of cooling of electronic components.

Originality/value

AWE is widely used in analyses of signal delays in electronic circuits, and rarely applied to mechanical systems. The present study applies AWE to heat transfer problems, and reveals that it reduces the computational time considerably. The results obtained are compared with conventional methods available in the literature, and they show good agreement. Hence the computational time is reduced, and the accuracy of results is verified.

To determine the optimal dimensions for a stacked micro‐channel using the genetic algorithms (GAs) under different flow constraints.

Abstract

Purpose

To determine the optimal dimensions for a stacked micro‐channel using the genetic algorithms (GAs) under different flow constraints.

Design/methodology/approach

GA is used as an optimization tool for optimizing the thermal resistance of a stacked micro‐channel under different flow constraints obtained by using the one dimensional (1D) and two dimensional (2D) finite element methods (FEM) and by thermal resistance network model as well (proposed by earlier researcher). The 2D FEM is used to study the effect of two dimensional heat conduction in the micro‐channel material. Some parametric studies are carried out to determine the resulting performance of the stacked micro‐channel. Different number of layers of the stacked micro‐channel is also investigated to study its effect on the minimum thermal resistance.

Findings

The results obtained from the 1D FEM analysis compare well with those obtained from the thermal resistance network model. However, the 2D FEM analysis results in lower thermal resistance and, therefore, the importance of considering the conduction in two dimensions in the micro‐channel is highlighted.

Research limitations/implication

The analysis is valid for constant properties fluid and for steady‐state conditions. The top‐most surfaces as well as the side surfaces of the micro‐channel are considered adiabatic.

Practical implications

The method is very useful for practical design of micro‐channel heat‐sinks.

Originality/value

FEM analyses of stacked micro‐channel can be easily implemented in the optimization procedure for obtaining the dimensions of the stacked micro‐channel heat‐sinks for minimum thermal resistance.

Abstract

This paper describes a generalized method of predicting the temperature distribution of the silicon chip with non‐uniform power dissipation patterns using Lagrangian interpolation function. A simplified heat sink thermal design was modeled to simulate a typical thermal design of microprocessor. Key thermal design parameters investigated are the heat source placement distance and level of heat dissipation. Verification of the proposed method was carried out by comparing the results with FEA predictions. Results of the verification show that the proposed method is reasonably accurate for practical purposes. A successful attempt has been made to predict the junction temperature of silicon chip with non‐uniform power distribution in a simple way.
