This paper deals with the design of an H∞-observer to estimate the state variables of the vertical car dynamics to be used for suspension control applications. The proposed methodology allows to cope with both the disturbance decoupling problem (for the road profile effects) and the implementation issue (through observer pole placement). The considered model is a 7 DOF full-car vertical model s...

This paper uses Côte d'Ivoire and Nigeria survey data on both supply and demand characteristics to examine how structural and demographic factors influence family planning provision and cost. The model, which takes into account the endogenous influence of service provision on average cost, explains provision well but poorly explains what influences service cost. We show that both size and speci...

PURPOSE To quantify the relation between eye and eyelids placement in different positions during downgaze and upgaze in healthy subjects. METHODS The position of the eye and eyelids of 10 healthy individuals was quantified by palpebral fissure image processing with NIH Image software. Upper and lower mid-pupil margin distance was measured in 7 positions: -30, -20, -10, 0, +10, +20 and +30 deg...

BACKGROUND The partial edentulous posterior mandible is often a challenge area that requires a bone reconstructive surgery for implants placement. PURPOSE This RCT was aimed to evaluate complications rate and vertical bone gain after Guided Bone Regeneration (GBR) with dense non-resorbable d-PTFE titanium-reinforced membranes (Group A) versus titanium meshes covered by cross-linked collagen m...

Vertical root fractures of endodontically treated teeth are a frustrating complication that leads to extraction. The aim of the current survey was to evaluate the role of operative procedures in the etiology of this complication. A total of 154 endodontically treated vertical root fractured teeth were cleaned and washed after extraction and maintained in individual vials. Periapical radiographs...

HYPOTHESES Vertical rectus abdominus myocutaneous flap reconstruction facilitates healing within the radiated pelvis and preserves the possibility of subsequent sexual function in patients with colorectal cancer who require partial or complete resection of the vagina. DESIGN A retrospective review of a consecutive series of patients. SETTING A tertiary referral center. PATIENTS All patien...

Preloading and Prefabricated Vertical Drains (PVD) is a ground improvement technique used to increase the consolidation process of clayey soils by means of shortening the drainage path. This paper discusses a case study of a road construction where a part of road alignment goes through a low laying water logged area. Primary consolidation of soft clay will continue for longer period of time aft...

BACKGROUND The purpose of this study was to compare the use of an extended vertical lower trapezius island myocutaneous flap (TIMF) and a pectoralis major myocutaneous flap (PMMF). METHODS A total of 39 patients with advanced recurrent oral and oropharyngeal squamous cell carcinoma (SCC) underwent salvage surgery followed by placement of either an extended lower vertical TIMF or PMMF for reco...

Initial ball flight characteristics of curve and instep kicks were investigated. Fifteen international female footballers performed curve and instep kicks from a distance of 20 m from goal and at a 1 m2 target. Seventeen Vicon cameras tracked three-dimensional coordinates of four reflective markers adhered to the ball. Ball flight characteristics were quantified, and the coordinates of the ball...
