In our approach, we use only the property (F1) of Wardowski while other authors employed all three conditions. Working only with the fact that the function F is strictly increasing on (0, +infinity)(m), we obtain as a consequence new families of contractive conditions in the realm of vector-valued metric spaces of Perov's type. At the end of the article, we present an example that supports obtained theoretical results and genuinely generalizes several known results in existing literature.

AB  - Many authors used the concept of F-contraction introduced by Wardowski in 2012 in order to define and prove new results on fixed points in complete metric spaces. In some later papers (for example Proinov P.D., J. Fixed Point Theory Appl. (2020)22:21, doi:10.1007/s11784-020-0756-1) it is shown that conditions (F2) and (F3) are not necessary to prove Wardowski's results. In this article we use a new approach in proving that the Picard-Jungck sequence is a Cauchy one. It helps us obtain new Jungck-Fisher-Wardowski type results using Wardowski's condition (F1) only, but in a way that differs from the previous approaches. Along with that, we came to several new contractive conditions not known in the fixed point theory so far. With the new results presented in the article, we generalize, extend, unify and enrich methods presented in the literature that we cite.

AB  - This paper considers the usage of Taguchi's contribution ratio as well as an adjusted Pareto diagram for determining the size of influential design factors in experimental design on output values in order to determine the best combination of input factors, as well as factors that can determine output. Two case studies that cover extreme examples are presented in that aim. The first case study examines one input workspace design distributed on tree experimental designs defining space coordinates. Every design has several output values that were measured. The second case study presents two experiments regarding injection of plastic molding process, with same input factors at parts which are different in material and dimensions with geometric deformations as output. It was shown that different experiments lead to different results, of which one is acceptable, while other is useless for further examinations. Accordingly, this paper gives guidelines how to use Taguchi's contribution ratio and Pareto diagram effectively in determination of influential factors in experiments.

AB  - Nowadays, a wide class of problems can be solved by using the classical newsboy model. However, in problems where uncertainty of events and randomness are omnipresent, there is a necessity to adapt the existing solutions and/or find new extensions that will properly answer all requirements. This paper considers a multistage assembly system where interrelated assembly operations with independent stochastic operation times should be planned in an optimal way. Delivery of items in a requested time implies that either delay costs or holding costs appear. The goal is to find optimal safety times. We propose an approximate technique based on successive application of the solution of simpler one-stage problem. The generalized mathematical model suggested is built up on the relaxed hypothesis and can be used in multistage assembly networks. The existence and uniqueness of the solution are proven. The preliminary tests are performed and our approximate technique is compared to exact results.

Delivery of items in a requested time implies that either delay costs or holding costs appear. The goal is to find optimal safety times. We propose an approximate technique based on successive application of the solution of simpler one-stage problem. The generalized mathematical model suggested is built up on the relaxed hypothesis and can be used in multistage assembly networks. The existence and uniqueness of the solution are proven. The preliminary tests are performed and our approximate technique is compared to exact results.",

AB  - We prove several fixed point theorems on cone metric spaces in which the cone does not need to be normal. These theorems generalize the recent results of Huang and Zhang (2007), Abbas and Jungck (2008), and Vetro (2007). Furthermore as corollaries, we obtain recent results of Rezapour and Hamlborani (2008).

AB  - Cilj rada je integracija vizuelnog dizajna sa dizajnom informacija.

Kao glavni zadatak, u ovom radu, je dizajnirana, projektovana i postavljena Web aplikacija za sračunavanje potencijala vodotokova. Analizirana je i proveravana upotrebljivost, produktivnost i funkcionalnost kako bi se omogućila validacija ovakvog rada imajući u vidu da izgradnja malih hidroelektrana, na za to povoljnim lokacijama, predstavlja i dobru priliku za investicije iz inostranstva, jer se radi o veoma unosnom i isplativom poslu. Izgradnja malih hidroelektrana bi znatno uticala i na kvalitet snabdevanja električnom energijom. Ovako urađena apikacija pruža velike mogućnosti nadogradnje kako u inženjerskom tako i u softverskom delu. Aplikacija je prilagođena svim Web browserima i svim rezolucijama monitora većim od 1024x768.

AB  - Prikazana su veoma precizne, originalne sonde sa zagrejanim vlaknima visoke prostorne i vremenske rezolucije i kalibracioni metod za turbulentna eksperimentalna istraživanja. Ovaj metod zahteva pozicioniranje V-sonde pod određenim uglom u odnosu na uniformnu brzinu mlaza otvorenog aerotunela. Iz dobijenog signala formira se kalibraciona matrica. Ocene odgovarajućih eksperimentalnih krivih su oblika Čebiševljevih polinoma, čime se vreme proračuna mernih tačaka značajno smanjuje. Ovaj kalibraciono-merni postupak zahteva manje pretpostavki nego u slučaju standardnih metoda zasnovanih na Kingovom zakonu.
AB  - Sophisticated equipment with unique hot wire V-probes, with high time and spatial resolution, and computer-aided calibration method for turbulence experimental research are described. This method requires the V-probe to be pitched in the uniform jet of the unique open calibration air tunnel at several velocities. From the outcome signal, a calibration array can be generated. Corresponding experimental curves are fitted with Chebishev polynomials, which decreases computational time. This method requires fewer assumptions than one based on the King's law.
