A novel approach for shape preserving contrast enhancement is presented in this paper. Contrast enhancement is achieved by means of a local histogram equalization algorithm which preserves the level-sets of the image. This basic property is violated by common local schemes, thereby introducing spurious objects and modifying the image information. The scheme is based on equalizing the histogram ...

The problem of minimally modifying a plan in response to changes in the specification of the planning problem has already been investigated in the literature. In this paper we consider the problem of non-minimal modification of plans from a computational point of view. We prove that while the general problem is intractable (that is, replanning from scratch is equally hard), there are scenarios ...

This paper deals with a modification of the CBCM method for floating nonlinear device characterization. Closed form analytical formulae for the estimation of CBCM errors due to parasitic charge injection are presented. A test chip implementing the method was designed and manufactured in the 0.35μm CMOS process. Key-Words: Charge-Based Capacitance Measurements, MOS characterization, Test Structures

We have probed the relationship between tubulin posttranslational modification and microtubule stability, using a variation of the antibody-blocking technique. In human retinoblastoma cells we find that acetylated and detyrosinated microtubules represent congruent subsets of the cells' total microtubules. We also find that stable microtubules defined as those that had not undergone polymerizati...

We present here the treatment of thirteen homosexuals by behaviour modification techniques. With classical electrical aversion and positive conditioning 8(61%) out of thirteen patients showed a change in orientation lasting on a six-month 1 year follow up. A marriageable age and indirect social pressures were positively correlated with improvement whereas the presence of a steady homosexual par...

Introduction: Slope streaks, commonly dark features in the high albedo, low thermal inertia, dust-rich equatorial regions of Mars, have been observed in images from all orbiting spacecraft since Mariner 9 [1-9] and are thought to fade or brighten over time due to mantling of dust [2,3,8]. Recent studies using images from the High Resolution Imaging Science Experiment (HiRISE) camera [10] have s...

Enzymatic modification of polyethersulfone (PES) membranes has been found not only feasible, but also an environmentally attractive way to vary surface properties systematically. In this paper, we summarize the effect of modification layers on protein adsorption and bacterial adhesion on PES membranes and surfaces. The enzyme laccase was used to covalently bind (poly)phenolic acids to the membr...

For an information-agent-based system to support virtual (Internet-supported) organisations, changes in environmental conditions often demand changes in organisational behaviour, i.e., organisational changes. As organisational behaviour relates to organisational structure, rethinking the structure of an organisation as environmental conditions demand so, renders such an organisation imperativel...

This paper provides a picture of using plasma treatment as a means for textile modification. It discusses the different modes for the generation of plasma. As plasma treatment is acting as a surface modification treatment, the paper also addresses the various types of plasmasubstrate interaction and their effects on the substrates. The use of plasma as a finishing application for different text...

Genetically-modified domestic animal models are of increasing significance in biomedical research and agriculture. As authentic ES cells derived from domestic animals are not yet available, the prevailing approaches for engineering genetic modifications in those animals are pronuclear microinjection and somatic cell nuclear transfer (SCNT, also known as cloning). Both pronuclear microinjection ...
