Positive L1 observer design for positive Switched systems

2014

Published version of an article in the journal: Circuits, Systems, and Signal Processing. Also available from the publisher at: http://dx.doi.org/10.1007/s00034-013-9737-6 This paper investigates the problem of L1 observer design for positive switched systems. Firstly, a new kind of positive L1 observer is proposed for positive switched linear delay-free systems with observable and unobservable subsystems. Based on the average dwell time approach, a sufficient condition is proposed to ensure the existence of the positive L1 observer. Under the condition obtained, the estimated error converges to zero exponentially, and the L1 -gain from the disturbance input to the estimated error is less t…

Research methods applied: scientific publications and previous conducted research results analysis and expert survey for possible financing model changes in Latvia. In exp…

Uzņēmuma "X" finanšu stāvokļa analīze

2016

Bakalaura darba tēmats ir “Uzņēmuma “X” finanšu stāvokļa analīze” – uzņēmuma īstais nosaukums nav noradīts pēc uzņēmuma vadības lūguma. Sabiedrība ar ierobežoto atbildību “X” tika izskatīta un analizēta no finanšu skata. Bakalaura darbs sastāv no trim galvenajām daļām. Pirmā nodaļā darba autors pārskata finanšu analīzes teorētiskus aspektus; otrajā nodaļā tiek norisināts uzņēmuma finanšu analīze un tika analizēti iegūtie rezultāti; darba trešajā nodaļā iegūtie rezultāti par uzņēmumu “X” – finanšu koeficienti – autors salīdzināja ar nozares vidējiem koeficientiem. Darba beigās, autors izdarīja secinājumus par veikto darbu un deva padomus, ka labāk uzlabot finanšu stāvokli uzņēmumā. Darba mēr…

SIA „Būvkompānija MBR” finansiālas darbības novērtēšana

2016

Diplomdarba mērķis ir, pamatojoties uz uzņēmuma SIA „Būvkompānija MBR” finanšu pārskatiem, novērtēt tā finansiālo stāvokli, attīstības tendences, identificēt uzņēmuma finanšu darbību kāvējošus faktorus un izstrādāt priekšlikumus uzņēmuma finansiālā stāvokļa uzlabošanai. Par diplomdarba pētniecisko bāzi autore pieņema SIA „Būvkompānija MBR” gada pārskatus par 2013., 2014., 2015. gadiem. Diplomdarba rakstīšanas gaitā autore veica pētamā uzņēmuma gada pārskatu sastāvdaļu analīzi, finanšu analīzes un maksātspējas rādītāju aprēķinu un rezultātu interpretēšanu, kā arī aprēķināto rādītāju salīdzinošo analīzi pa gadiem. Diplomdarba noslēgumā autore dod secinājumus par pētījuma rezultātiem, priekšli…

STUDY OF SAGITTAL SPINAL ROM IN ELDERLY WOMEN AFTER A SPECIFIC FLEXIBILITY-TRAINING PROGRAM

2013

The reduction of spinal mobility is one luckless consequence of the aging process. In particular, scarcity of exercise appears to be the principal reason of aging-related spinal dysfunction syndrome, which is characterized by adaptive shortening of soft tissue and a partial loss of range of spinal motion (1). Several recommendations promoting the spinal flexibility in elderly people are based on stretching programs that include static and ballistic exercises and PNF techniques (2). Several studies showed that specific training programs could improve body balance (3), bodyweight distribution on feet (4), muscle strength and flexibility (5) in elders. In particular, Imagama et al. (2011) show…

3PC-030 Physical, chemical and microbiological stability of sirolimus 0.4% in topical formulations

2019

Background Facial angiofibromas in tuberous sclerosis are an aesthetic problem within the clinical context of the disease. There are currently few stability studies that allow selecting the best topical sirolimus therapy. Purpose To improve the formulation of sirolimus 0.4% for the treatment of facial angiofibromas in tuberous sclerosis and to determine the period of validity (physical, chemical and microbiological stability) of the proposed formulations. Material and methods Three formulations of sirolimus 0.4% were prepared (each in duplicate, A and B). Facilities and equipment: biological safety cabinet with individual protection equipment for the manipulator. Conditions: aluminum tubes,…

Recent advances in the application of microbial transglutaminase crosslinking in cheese and ice cream products: A review

2018

Microbial transglutaminase (MTGase) has been currently utilized to form new food structures and matrices with high physicochemical stability. Incorporation of this multi-functional enzyme into structural composition of milk protein-based products, such as cheese and ice cream, can not only be a successful strategy to improve their nutritional and technological characteristics through intramolecular cross-linking, but also to reduce the production cost by decreasing fat and stabilizer contents. The recent research developments and promising results of MTGase application in producing functional formulations of cheese and ice cream with higher quality characteristics are reviewed. New interest…

Impact of electron beam irradiation on fish gelatin film properties

2016

International audience; The objective of this work was to display the effect of electron beam accelerator doses on properties of plasticized fish gelatin film. Electron spin resonance indicates free radical formation during irradiation, which might induce intermolecular cross-linking. Tensile strength for gelatin film significantly increases after irradiation (improved by 30% for 60 kGy). The vapour permeability is weakly affected by irradiation. Surface tension and its polar component increase significantly and are in accordance with the increase of wettability. So, irradiation may change the orientation of polar groups of gelatin at the film surface and crosslink the hydrophobic amino aci…
