Members of boards of directors of large corporations who also serve together on an outside board, form the so called interlock graph of the board and are assumed to have a strong influence on each others’ opinion. We here study how the size and the topology of the interlock graph affect the probability that the board approves a strategy proposed by the Chief Executive Officer. We propose a meas...

Labomat 3 is a recon gurable platform for teaching and research purposes developed by our laboratory. In this paper we describe in details the hardware and software of the board as well as three application domains: logic design, computer architecture, and codesign. The main features of the board are: a microprocessor associated with two mid-range FPGAs; a set of powerful software tools going f...

Multi-chip, board-level designs form a large portion of today’s digital system designs. Unfortunately, traditional methods for debugging these designs, such as wire wrap, prototype fabrication and software simulation, are inadequate. Wire-wrap is complex and error-prone, prototype fabrication is time-consuming and it is difficult to isolate errors, and simulation is too slow for full testing. R...

The behavior of composites depends crucially on the distribution of local …elds. The ways to characterize and …nd such distributions are poorly understood. In this paper, an attempt is made to present some simple approximate formulas for distributions of the local …elds in variational problems. They are given in an explicit form for thermo-elastic composites and heat-conducting composites. The ...

In this paper, the authors report on work done for an ESA project entitled “Mars Mission Onboard Planning and Scheduling” (MMOPS), exploring a limited form of onboard reasoning for space-related robotic systems. Striking a middle ground between ground-based and on-board planning, the authors describe experiments with an on-board “planning assistant” which repairs plans using “Timeline Validatio...

We have designed, produced, and experimentally characterized 2.7 mm thick composite panels having negative refractive index between 8.4 and 9.2 GHz. The composite metamaterial is fabricated using conventional commercial multilayer circuit-board lithography; three-dimensional physical (as opposed to electromagnetic) structure is introduced by the use of vias to form sections of the scattering el...

Conflict of Interest Disclosures: All authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest. Drs Krumholz and Ross receive support fromMedtronic to developmethods of clinical trial data sharing, from the Centers of Medicare &Medicaid Services to develop and maintain performancemeasures that are used for public reporting, and from the Food and Drug...

To fully exploit the capabilities of satellite−borne multi−hyperspectral sensors, some form of image compression is required. The Gelli−Poggi coder, based on segmentation and class−based transform coding, has a very competitive performance, but requires some a−priori knowledge which is not available on−board. In this paper we propose a new version of the Gelli−Poggi coder which is fully unsuper...

nowadays in consequence of widespread changes of corporate governances, chairman of the board has more real authorities on company decisions and due to his significant role in board leadership, is under the pressure of performance expectations. however, these changers are not made as it deserves in iran and in spite of various effects of chairman leadership on board culture – especially team pr...
