In this talk I will try to review some of the early experimrnts in the field of electron-proton scattering, concent.rnt,ing mostly on t,he inelastic scattering rxperimentn at SLAC. Ordinarily, t,hose experiments would be covered in the first. five or ten minutes of the talks by Professors Sruilli and Drrll, but (.his is a special yrar, and I will fwl free t.o rrminisce about the early days in a...
In this working note, we sketch out some current thoughts on the use of “views” in a knowledge-base. A view is an explicit representation of how a general concept can be applied to a domain-specific concept. By making views explicit, we can control which, and how, more general concepts can be used to represent a domain-specific concept. We also discuss the use of views to select alternative the...
We consider alternative theories of gravity with a direct coupling between matter and the Ricci scalar We study the relation between these theories and ordinary scalar-tensor gravity, or scalar-tensor theories which include nonstandard couplings between the scalar and matter. We then analyze the motion of matter in such theories, its implications for the Equivalence Principle, and the recent cl...
Recently, a growing interest has emerged on the development of new and efficient energy sources, due to the inevitable extinction of the nonrenewable energy reserves. One of these alternative sources which have a great potential and sustainability to meet up the energy demand is biomass energy. This significant energy source can be utilized with various energy conversion technologies, one of wh...
In this study, the interaction between NO2+ cation and Hen (n = 1-7) clusters is investigated by means of ab initio calculations at MP2/aug-cc-pVTZ and QCISD/aug-cc-pVTZ computational levels. The first and second solvation shells were obtained while N atom of NO2+ interacts with five and two He atoms, respectively. Stabilizat...
We study the hydrodynamics of the high-energy phase of Little String Theory. The poles of the retarded two-point function of the stress energy tensor contain information about the speed of sound and the kinetic coefficients, such as shear and bulk viscosity. We compute this two-point function in the dual string theory and analytically continue it to Lorentzian signature. We perform an independe...
Performance of building Energy Management Systems (EMS) has been controversial in several studies due to lack of measured energy savings, changes in building use or operation, other changes that simultaneously affect building energy use, equipment malfunction, or weather normalization. This study evaluated energy savings in 20 buildings that have EMS installed to control HVAC. The buildings wer...
This paper is based on lectures given in Ladek-Zdroj, Poland during the 42nd edition of the Karpac winter school on Theoretical Physics. The aim of these lectures was to give an introduction to a rigorous, mathematically well based, variational approach to alternative theories of Gravity, in view of their very interesting recent applications in the framework of Cosmology. We discuss alternative...
This paper presents a novel Nonlinear Model Predictive Control (NMPC) scheme for underwater robotic vehicles operating in a constrained workspace including static obstacles. The purpose of the controller is to guide the vehicle towards specific way points with guaranteed input and state constraints (i.e obstacle avoidance, workspace boundaries). The proposed scheme incorporates the full dynamic...
In most global fits of the constrained minimal supersymmetric model (CMSSM) to indirect data, the a priori likelihoods of any two points in tanβ are treated as equal, and the more fundamental μ and B Higgs potential parameters are fixed by potential minimization conditions. We find that, if instead a flat prior measure on μ and B is placed, a strong preference exists for the focus point region ...
