Circuit level modelling of spatially distributed mm and sub mm-wave systems
1998 IEEE Sixth International Conference on Terahertz Electronics Proceedings. THZ 98. (Cat. No.98EX171), 2002Modelling of millimeter-wave and submillimeter-wave systems have generally been developed from a circuit perspective with the effect of the electromagnetic environment modeled essentially as lumped elements. Recent developments in steady-state and transient analyses integrating circuit and electromagnetic modeling are presented.

Comparison of a 5‐mm and 10‐mm vessel sealing device in an open ovariectomy model in dogs
Veterinary Record, 2017The objectives of this study were to compare (1) the extent of thermal damage and (2) the time between the 5‐mm LigaSure V (LS5) and 10‐mm LigaSure Atlas (LS10) vessel sealing devices (VSD) when performing open ovariectomy in dogs. A prospective, randomised, clinical trial was performed in 40 client‐owned sexually entire female dogs.

How Accurate Are QM/MM Models?
The Journal of Physical Chemistry ADespite the success and widespread use of QM/MM methods in modeling (bio)chemically important processes, their accuracy is still not well understood. A key reason is because these methods are ultimately approximations to direct QM calculations of very large systems, which are impractical to perform in most cases. We highlight recent progress toward the

Endogenizing Exogenous Default Barrier Models: The MM Algorithm
SSRN Electronic Journal, 2012Abstract In this paper, we propose a Maximization–Maximization ( MM ) algorithm for the assessment of hidden parameters in structural credit risk models. Step M1 updates the value, volatility, and expected return on the firm’s assets by maximizing the log-likelihood function for the time series of equity prices; Step M2 updates the default ...

A Trace Specification of the MMS Security Model
1988Abstract : The trace language provides for the specification of software modules in terms of the effects (such as return values) that the user sees when s(he) executes a sequence of procedure and function calls. These sequences are called traces. A trace specification consists of a syntax section and a semantics section.

MMS-IU Model for Incremental Update of Spatial Database
2013The update quality of spatial database determines the data’s value. Combined with the characteristics of the spatial database updating, we studied incremental updates modeling of the spatial database and supported a multi-mode update model, which referred to as the MMS-IU. The model has two features: (1) it contains two different update ways to enhance

Noise Model of the Galileo “mm-Clock”
2018Galileo is the first GNSS system equipped with a highly stable H-maser. In this section we conduct a comprehensive analysis of the performance of the Passive H-Maser (PHM) used as a primary clock on board Galileo navigation satellites. PHM ground test results are compared to the clock parameters estimated from the MGEX data.

Mining Infrequent Itemsets Based on Extended MMS Model
2007When we study positive and negative association rules simultaneously, infrequent itemsets become very important because there are many valued negative association rules in them. However, how to discover infrequent itemsets is still an open problem. In this paper, we propose an extended multiple minimum supports (XMMS) model to constrain infrequent ...
