We investigate the sparse eigenvalue problem which arises in various fields such as machine learning and statistics. Unlike standard approaches relying on approximation of the l0norm, we work with an equivalent reformulation of the problem at hand as a DC program. Our starting point is the eigenvalue problem to which a constraint for sparsity requirement is added. The obtained problem is first ...

setback in elevation of a structure is a special irregularity with considerable effect on its seismic performance. this paper addresses multistory reinforced concrete (rc) frame buildings, regular and irregular in elevation. several multistory reinforced concrete moment resisting frames (rcmrfs) with different types of setbacks, as well as the regular frames in elevation, are designed according...

The article compares the provisions of legal regulations on remote form education with actual scope their application in academic environment. research method used was an analysis documents such as Constitution Republic Poland, Act ‘Law Higher Education and Science’, Ministry Science internal (Orders UR). aim to compare found aforementioned practical realities higher education, while case study...

STANDARD OF REFERENCE Built and developed with the assistance of scientists closely associated with problems relating to airborne particles such as fungus spores and pollens, the sampler has proved to be a standard of reference throughout the world. Although the instrument compares closely to the trap described by Hirst in 1952 (Ann app. Biol 39 pp. 257-265) its performance has been enhanced by...

CASPA is a stochastic process algebra tool for performance and dependability modelling, analysis and verification. It is based entirely on the symbolic data structure MTBDD (Multi-Terminal Binary Decision Diagram) which enables the tool to handle models with very large state space. This paper describes an extension of CASPA’s solving engine for path-based approximation of MTTFF (Mean Time To Fi...

Introduction: Tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .This paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  Materials and Methods: Sixty re...

requires more than trillion years on Wiener's machine 20]. Its main advantage is that organizations can increase the security of their systems which use DES in hardware, with the same encryption/decryption speed. An additional advantage is the backward compatibility to the standard DES, that can be achieved by choosing K a = K b = 0 and K c which does not modify the order of the S-boxes. Table ...

introduction: this is a descriptive study to study the conditions of hospital libraries at iran ,tehran and shahid beheshti university of medical sciences and compares the staff, printing sources, services and physical situations with “standards for hospital libraries 2002” and “standard of educational and treatment center library collection”. methods: this survey has been done on 35 hospital l...

While pollution reduction remains a common policy priority, no consensus exists on how best to stimulate needed action. This paper compares the effectiveness of relative and absolute performance standards in motivating emissions cleanup by stationary polluters. Using a unique panel characterizing Chilean pollution sources, I examine a natural experiment created by a change in the performance st...

This paper compares the predictive performance and efficiency of several machine-learning methods when applied to a genome-wide dataset on Alzheimer's disease that contains 312,318 SNP measurements on 1411 cases. In particular, a Bayesian algorithm is introduced and compared to several standard machine-learning methods. The results show that the Bayesian algorithm predicts outcomes comparably t...
