This paper uses ALIS data to compare academic performance in two subjects often viewed as relatively close substitutes for one another at A-level. The important role of GCSE achievement is confirmed for both subjects. There is evidence of strong gender effects and variation in outcomes across Examination Boards. A counterfactual exercise suggests that if the sample of Business Studies candidate...

Tohoku University, Japan is developing a new hand-held land mine detection dual-sensor (ALIS) which is equipped with a metal detector and a GPR. ALIS is equipped with a sensor tracking system, which can record the GPR and Metal detector signal with its location. The Migration processing drastically increases the quality of the imaging of the buried objects.Evaluation test of ALIS has been condu...

for the first time in the minkowski space, an rn 1 time-like complementary ruled surface isdescribed and relations are given connected with an asymptotic and tangential bundle of the time-likecomplementary ruled surface. furthermore, theorems are given related to edge space, central space andcentral ruled surface of this complementary ruled surface.

The paper is partly based on research done for the EU-funded (IST2004-2.4.9) project ALIS (Automated Legal Intelligent System) on Intellectual Property Law. We describe the development process of the ALIS Intellectual Property ontology from both a legal and a technical perspective. We discuss the scope and the features of this IP ontology, the lessons learned, and the problems solved. This is d...

A European campaign of ground-based radar, lidar and optical measurements was carried out during the winter of 1996/1997 (28 December±2 February) to study lee waves in the northern part of Scandinavia. The participants operated ozone lidars, backscatter lidars and MST radars at ALOMAR/Andoya and Esrange/Kiruna, and an ALIS imaging system in Kiruna. The Andoya site was generally windward of the ...

Over the past decade, the civil engineering community has ever more realized the importance and perspective of the reliability-based design optimization (RBDO), the selection of a design that satisfies performance constraints with a specified probability. Since then several stochastic simulation algorithms for computing small failure probabilities encountered in reliability analysis of engineer...

objective: infection control is one of the important aspects in dentistry. oral and maxillofacial surgery is one of the most sensitive fields in dentistry in which infection control is important a sterile surgical set is imperative. manufacturers only guarantee the sterility of the anesthetic not the sterility of its outer surface. they recommend alcohol to sterile the outer surface (especially...

The quadrics are all surfaces that can be expressed as a second degree polynomialin x, y and z. We study the Gauss map G of quadric surfaces in the 3-dimensional Euclidean space R^3 with respect to the so called L_1 operator ( Cheng-Yau operator □) acting on the smooth functions defined on the surfaces. For any smooth functions f defined on the surfaces, L_f=tr(P_1o hessf), where P_1 is t...

In this paper, we classify surface at a constant distance from the edge of regression on translation surfaces of Type 1 in the three dimensional simply isotropic space I^1_3 satisfying some algebraic equations in terms of the coordinate functions and the Laplacian operators with respect to the first, the second and the third fundamental form of the surface. We also give explicit forms of these ...
