The removal of Total and Volatile Suspended Solids (TSS/VSS) was studied in a pilot-scale UASB (Upflow Anaerobic Sludge Bed) reactor treating settled sewage under subtropical conditions (Salta, Argentina). The effect of sludge bed height (hsb) and upflow velocity (Vup) on the removal of TSS and VSS was assessed. TSS and VSS removal efficiencies of up to 95% have been achieved when Vup ≤ 0.43 m/...

Stochastic programs are usually hard to solve when applied to real-world problems; a common approach is to consider the simpler deterministic program in which random parameters are replaced by their expected values, with a loss in terms of quality of the solution. The Value of the Stochastic Solution—VSS—is normally used to measure the importance of using a stochastic model. But what if VSS is ...

With the rapid development of MANET, secure and practical authentication is becoming increasingly important. The existing works perform the research from two aspects, i.e., (a)secure key division and distributed storage, (b)secure distributed authentication. But there still exist several unsolved problems. Specifically, it may suffer from cheating problems and fault authentication attack, which...

Visual secret sharing (VSS) scheme is a perfect secure method that protects a secret image by breaking it into shadow images (called shadows). Unlike other threshold schemes, VSS scheme can be easily decoded by the human visual system without the knowledge of cryptography and cryptographic computations. However, the size of shadow images (i.e., the number of columns of the black and white matri...

Background Ophthalmic outcomes following venous sinus stenting (VSS) in patients with idiopathic intracranial hypertension (IIH) are not well characterized. Materials and Methods A retrospective chart review was conducted on 86 consecutive IIH who underwent at Mayo Clinic, Rochester, Minnesota Stanford Medical Center, Palo Alto, California between May 2015 October 2021. Patients raised pressure...

BACKGROUND Volume of distribution is an important pharmacokinetic property that indicates the extent of a drug's distribution in the body tissues. This paper addresses the problem of how to estimate the apparent volume of distribution at steady state (Vss) of chemical compounds in the human body using decision tree-based regression methods from the area of data mining (or machine learning). Hen...
