Despite many studies already published on large intelligent surfaces (LIS), there are still some gaps in mathematical models the face of possible scenarios. In this work, we evaluate performance a single-input single-output (SISO) system which an LIS acts as controllable scatterer. We consider that direct link between transmitting and receiving devices is non-existent due to blockage. Quantizat...

The residential gateway is a device that has become an integral part of home networking equipment. Discovering a Location Information Server (LIS) is a necessary part of acquiring location information for location-based services. However, discovering a LIS when a residential gateway is present poses a configuration challenge, requiring a method that is able to work around the obstacle presented...

In contrast to animals, plant germ cells are formed along with accessory cells in specialized haploid generations, termed gametophytes. The female gametophyte of flowering plants consists of four different cell types, which exert distinct functions in the reproductive process. For successful fertilization, the development of the four cell types has to be tightly coordinated; however, the underl...

Purpose: To cope with changes in user information behaviour and needs, libraries and information services (LIS) must find manageable ways for on-going research and improvement. A model for a manageable research cycle was piloted at the Central Cancer Library, The Netherlands Cancer Institute (Amsterdam). Approach: Institute employees (24) (users and non-users of the Central Cancer Library; most...

Electroencephalography (EEG) has been proposed as a supplemental tool for reducing clinical misdiagnosis in severely brain-injured populations helping to distinguish conscious from unconscious patients. We studied the use of spectral entropy as a measure of focal attention in order to develop a motor-independent, portable, and objective diagnostic tool for patients with locked-in syndrome (LIS)...

Sign languages are visual-gestural languages developed mainly in deaf communities; their tempo-spatial nature makes it difficult to write them, yet several transcription systems are available for them. Most sign languages dictionaries interact with their users via a transcriptionbased inteface; thus their users need to be expert of their specific transcription system. The e-LIS dictionary is th...

Purpose – To show that the neo-pragmatist position of Richard Rorty, when combined with a sociocultural perspective, provides library and information science (LIS) with a forceful epistemological tool. Design/methodology/approach – Literature-based conceptual analysis of: historical development of pragmatism in relation to other epistemological positions; neo-pragmatism as a non-dualist, both p...

INTRODUCTION The Locked-In syndrome (LIS) is defined by: (i) the presence of sustained eye opening (bilateral ptosis should be ruled out as a complicating factor); (ii) preserved awareness; (iii) aphonia or hypophonia; (iv) quadriplegia or quadriparesis; and (v) a primary mode of communication that uses vertical or lateral eye movement or blinking. Acute ventral pontine lesions are its most com...

Purpose – To provide an analysis of the notion of “information poverty” in library and information science (LIS) by investigating concepts, interests and strategies leading to its construction and thus to examine its role as a constitutive element of the professional discourse. Design/methodology/approach – Starting from a Foucauldian notion of discourse, “information poverty” is examined as a ...

Given a sequence π1π2 . . . πn, a longest increasing subsequence (LIS) in a window π〈l, r〉= πlπl+1 . . . πr is a longest subsequence σ = πi1πi2 . . . πiT such that l ≤ i1 < i2 < · · · < iT ≤ r and πi1 < πi2 < · · · < πiT . We consider the Lisw problem, which is to find the longest increasing subsequences in a sliding window of fixed-size w over a sequence. Formally, it is to find a LIS for ever...
