We present a theory for reduced-order modelling of linear time-varying systems, together with efficient numerical methods for application to large systems. The technique, called TVP (Time-Varying Padk), is applicable to deterministic as well as noise analysis of many types of communication subsystems, such as mixers and switched-capacitor filters, for which existing model reduction techniques c...

First order partial differential equations (PDE) are often the main tool to model problems in optimal control, differential games, image processing, physics, etc. Dependent upon the particular application, the boundary conditions are specified either at the initial time instant, leading to an initial value problem (IVP), or at the terminal time instant, leading to a terminal value problem (TVP)...

Tourism forecasting plays an important role in tourism planning and management. Various forecasting techniques have been developed and applied to the tourism context, amongst which econometric forecasting has been winning an increasing popularity in tourism research. This paper therefore aims to introduce the latest developments of econometric forecasting approaches and their applications to to...

• In the FAVAR, Monetary Policy Uncertainty (MPU) shocks are recessionary. Firm entry decreases and firm exit increases amplifying responses to MPU shocks. The stock price declines, while TFP in response model with dynamics replicates FAVAR-IRFs outperforms standard medium-scale DSGE model. This paper uses a FAVAR external instruments show that monetary policy uncertainty recessionary associate...

Faecal moisture content can determine whether faeces appear soft or firm, and faecal character can influence whether owners are satisfied with a dog food. In a previous study, dogs appeared to produce softer faeces after noon. The purpose of the present study was to determine whether time of defecation affected canine faecal water content. A total of eight hound dogs were fed one of four canned...

This paper analyzes whether a wealth of information contained in 126 monthly series used by large-scale Bayesian Vector Autoregressive (LBVAR) models, as well as Factor Augmented Vector Autoregressive (FAVAR) models, either Bayesian or classical, can prove to be more useful in forecasting real house price growth rate of the nine census divisions of the US, compared to the small-scale VAR models...

OBJECTIVES To evaluate a new technique, the rectal balloon (RB), to control blood loss after transvesical prostatectomy (TVP). PATIENTS AND METHODS Over 2 years 100 patients were prospectively randomised into two equal groups. All patients underwent TVP for their benign prostatic hyperplasia but a RB (a balloon fixed to a three-way Foley catheter tip by a plaster strip, making it airtight) wa...

The target visitation problem (TVP) is concerned with finding a route to visit a set of targets starting from and returning to some base. In addition to the distance traveled a tour is evaluated by taking also preferences into account which address the sequence in which the targets are visited. The problem thus is a combination of two well-known combinatorial optimization problems: the travelin...

Introduction: La maladie thromboembolique veineuse (MTEV) présente par ses deux entités cliniques: thrombose veineuse profonde (TVP) et embolie pulmonaire (EP), est une pathologie fréquente ayant une forte morbi-mortalité. En Algérie, cette pathologie prend de plus en plus de l'ampleur, en l'absence de toute publication révélant sa fréquence et le pouvoir thrombogène des facteurs de risque qui ...

BACKGROUND The persistence of significant tricuspid regurgitation (TR) after percutaneous mitral valvuloplasty (PMV) is known to be an independent predictor of adverse outcome in mitral stenosis (MS). However, it remains unclear whether mitral valve (MV) surgery combined with surgical correction of TR is the better treatment option than PMV in patients with severe MS and severe functional TR. ...
