LXXV.—Overvoltage tables. Part I. Cathodic overvoltages

Speaking Stata: Problems with tables, Part I

Tables in some form or another are part and parcel of data management and analysis. The main general-purpose tabulation commands, tabulate, table, and tabstat, are reviewed and compared. When these do not provide a tabulation solution, one key strategy is to prepare the material for tabulation as a set of variables, after which the table itself can be presented with tabdisp or list. This is the...

Transient Overvoltages in Power System

There are many reasons for over voltages in power system. The overvoltage causes number of effect in the power system. It may cause insulation failure of the equipments, malfunction of the equipments. Overvoltage can cause damage to components connected to the power supply and lead to insulation failure, damage to electronic components, heating, flashovers, etc. Over voltages occur in a system ...

Part I : Part Ii : Part Iii : Part Iv

The theory of stick-slip is developed, based on the concept of a static and dynamic coefficient of friction. The dynamic coefficient is assumed to be independent of displacement and to depend wholly on normal stress across the surface. It is also assumed to be velocity-independent. The theory predicts that the stress drop during stick-slip is independent of machine stiffness. The displacement d...

Distal Approaches in Patellofemoral Pain: A Systematic Review, Part I

Purpose: Increased patellofemoral joint reaction force (PFJRF) is the main cause of patellofemoral pain syndrome (PFP). Foot pronation causes faulty joint coupling of the lower limb and increases the PFJRF. Therefore, the aim of systematic review is effect of the distal interventions on the clinical symptoms and kinematic of PFP patients.   Methods: The search strategy was carried out from Goo...
