We introduce a new class of dynamical systems that we call "linear complementarity systerns". The evolution of these systems typically consists of a series of continuous phases separated by "events" which cause a change in dynamics and possibly a jump in the state vector. The occurrence of events is governed by certain inequalities similar to those appearing in the Linear Complementarity Proble...

The convulsant activity of pentylenetetrazol (PTZ) , is mainly due to' its ability to selectively antagonize GABA mediated post synaptic inhibition in the mammalian brain though a direct excitatory effect on neuronal membranes cannot be ruled out as a contributory factor (1). Furthermore there are reports which indicate that 5-hydroxytryptamine (5-HT) and norepinephrine (NE) playa modulatory ro...

The neats: proponents of formal-based, knowledge-intensive smart systems to revolutionize the requirements process. The eventual success of the neat approach is less certain. There are several opinions of the answer to: ‘Can the neats ever playa significant role in requirements engineering?’: a. Never – the extra effort of doing things the neat way will always exceed the payoff. b. Hardly ever ...

Meteorological data from stations around and within the Kaimai Ranges and data from temporary sites are used to characterise the climate of the ranges. Lowland climate is warm temperate with ample rainfall but the upland region is cooler, wetter and frequently enveloped in fog. Frequent fog plays an important part in the climate of upland regions. By modifying light, moisture and temperature re...

The Context Scenario Planning is fast becoming one of the most popul(lr and persuasive tcchniques, used in strategic plan ni ng and foresighting cxercises of aU kinds in both public and private sectors, It is likely that the approach will playa more prominent role in helping organisations and agencies from all parts of the economy, governance and society in Ireland think, talk, act and plan d i...

Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this combinatorial image analysis 13th international workshop iwcia 2009 playa del carmen me...

Dust sources have been revealed through remote sensing, first regionally by ~1° resolution sensors (TOMS), then at sub-basin scale moderate-resolution (MODIS). Sensors with higher spatial until recently were poorly temporally-resolved, precluding their use for systematic investigations of sources. Now, “CubeSat” constellations high-temporal-and-spatial-resolution such as PlanetScope offer ~3 m ...
