This paper examines strategies of standard software vendors, in view of the existence of network effects on standard software markets. In particular, we analyze if and under which conditions penetration pricing can be considered as a promising strategy. Our work is based on a simulation model, which provides the opportunity to examine the impact of alternative pricing strategies on the distribu...

TBM boreability and performance prediction has always been a hot research topic. In this paper, taking one large diameter long tunnel excavated by gripper hard rock in Northeastern China as background, based on number of boring data site mono-factorial regression analysis the correlations among Field Penetration Index (FPI) geological parameters, multi-factorial correlation formula FPI with uni...

Nine new dihydrochloride salts of 3-(4-arylpiperazin-1-yl)-2-hydroxypropyl 4-alkoxyethoxybenzoates were designed and synthesized. The physicochemical properties such as lipophilicity index (log kw) and dissociation constant (pKa) were experimentally determined and compared to the software calculated data. The lipophilicity index was determined by means of reversed-phase high performance liquid ...

We describe a method of delivering light to biological samples using a planar waveguide structure with a symmetric cladding environment. The symmetry of the waveguiding structure allows the penetration depth of the evanescent field to be tuned over a wide range by varying the thickness and/or refractive index of the waveguide. Furthermore, the symmetrical structure facilitates efficient excitat...

BACKGROUND Obesity is a significant risk factor for surgical site infections (SSIs), for poorly understood reasons. SSIs are a major cause of morbidity, prolonged hospitalization, and increased health care cost. Drug disposition in general is frequently altered in the obese. Preoperative antibiotic administration, achieving adequate tissue concentrations at the time of incision, is an essential...

Conventional drilling of rock, in most mining applications, uses the mechanical impact of a metal tool to create the advancing hole. This technique, which has gradually increased in power and thus penetration rate has, however, certain inherent disadvantages. These range from the overall weight of the equipment which must be located at the free face of the hole to the maintenance of alignment o...

In this study, we explore the global effect of the Internet on democracy over the period of 1992 to 2002 by observing the relationships between measures related to democracy and Internet prevalence. Our findings suggest that while Internet usage was not a very powerful predictor of democracy when examining full panel data from 1992 to 2002, it was a stronger predictor when we study data from ju...

The need for a drying stress indicator has previously been stated with some research in the past to this means. Given the recent successes in achieving this goal through monitoring shrinkage, the refinement and further understanding of the process was needed, specifically, the influence that penetration of the mount-foot had on the shrinkage data. Four different LVDTmounts were investigated in ...

Following previous presentations on the dangers penetration testers face in using current off-the-shelf tools and practices (Pwn the Pwn Plug and I Hunt Penetration Testers), this paper and presentation explores how widely available learning materials used to train penetration testers lead to inadequate protection of client data and penetration testing operations. Widely available books and oth...
