Renal colic caused by kidney stone or urolithiasis is common diagnosis in Urology departments worldwide. There are projections that during lifetime 13% of men and 7% of women will get a kidney stone. The incidence of stone formation is determined by ethnicity, geographical and climatic features as well as genetic factors and diet. The prevalence of kidney stones is between 1% and 20%. Approximately, every fifth visit to emergency Urology department in Split, Croatia is a result of acute flank pain. To support the clinical diagnosis appropriate imaging is performed, ultrasound with kidney-ureter-bladder X-ray and/or CT scan. X-ray imaging is most used technique because of its' availability and low ionizing radiation exposure. The problem encountered is lack of sensitivity and specificity what leads to low dose CT scans to confirm the diagnosis. It would be of great help for clinicians to compare images of kidney-ureter-bladder X-ray images to more specific and sensitive CT scans to improve the diagnosis based on X-ray only.

Stretchable materials are frequently studied for the realization of strain sensors. The variation of the sheet impedance when an external mechanical stimulus is applied is employed to develop strain sensors. Several strain sensors have been proposed that use these materials but most of these require a hardwired system for sensor reading. Here a simple fully wireless strain sensor is proposed. The structure comprises a periodic surface whose elementary cell provides variable absorption as a function of the stretchable material sheet impedance.

Due to climate change, the EU Green deal and initiatives from Glasgow COP 26 require intensive mitigation measures toward decarbonisation of the buildings sector. One of the biggest challenges for achieving CO2 reduction goals will be the residential sector, especially multi residential buildings. Although there are well-known technologies and energy efficiency (EE) measures that can greatly contribute to decarbonisation of buildings, experience shows that the main barriers for implementation of EE measures originate from the potential client side and have social, economic and regulatory character. These barriers include: lack of awareness about climate change and necessity for urgent actions and long payback period for investment. On the other hand, market and ESCO company side barriers predominantly have economic and technical character, such as a lack of integrator who has professional capability to implement deep renovation projects as well as financial capability for investing in energy service through ESCO model with a long return of investment. Although there is different definition of ESCO model in the world and it is evolving and the model has been implemented for decades there is a little progress in implementation of such model in multi residential building sector. Additionally, there is a necessity for deep renovation of buildings where ESCO model is not desirable due to long payback period. However, there is a new reality now after two years of COVID pandemic and recent EU decision to dramatically decrease its dependency on fossil fuels through the REPowerEU plan. These have created new circumstances and drivers for intensive rethinking of implementation of ESCO model in multi residential buildings. This paper discusses barriers and drivers with associated risks for implementation of ESCO model in the residential sector and gives future direction of actions for implementation of this model in multi residential buildings. Barriers and drivers discussed in this paper also reflect practice and experience on the ESCO market in Croatia.

Metal Matrix Composite materials (MMC) are usually made by dispersing a reinforcing material embedded and completely continuous in a monolithic material or metal matrix. The reinforcing material can be metal, ceramic or an organic compound that provides the MMC with an increase in stiffness, strength, conductivity, corrosion resistance, thermal properties, wear resistance and fatigue life. Its manufacture requires considerable energy and raw material, since the matrix material must be fused in a furnace. In recent years, the valuation of waste, as well as the reduction of the impact of the product or process on the environment, has forced the use of some material waste for the manufacture of new composite materials. Life cycle assessment (LCA) is a tool that is used to evaluate the consumption of energy and raw materials, and the impact of waste and emissions of a product or process on the environment. This work proposes a comprehensive studio to determine the yield stress, tensile strength and toughness, as well as the LCA of the manufacturing process of a novel composite material that is composed of EN AW 6082 recycled aluminum alloy matrix reinforced with bidirectional continuous fibers of AISI 304 stainless steel. Five wire diameters and wires spacing oriented at 0°were studied. These were: Ø0.32 mm x 1.41 mm, Ø0.5 mm x 1.81 mm; Ø0.6 mm x 2.177 mm; Ø0.75 mm x 2.72 mm and Ø0.8 mm x 2.7828 mm. The results were compared to those of unreinforced EN AW 6082 recycled aluminum matrix without its bidirectional continuous fibers. The combination of wire diameter wire spacing of 0.8 mm x 2.828 mm provided an increase in tensile strength of 136% over than of unreinforced aluminum. Moreover, the combination of Ø0.32 mm x 1.41 mm and Ø0.8 mm x 2.828 mm gave an increase in toughness of 25%, whereas the combination of Ø0.6 mm x 2.177 mm gave an increase in toughness of 175%. Also, some of the environmental impacts of the manufacturing process of the proposed MMC for each of the five diameters and wires spacing studied hardly varied considerably with respect to unreinforced aluminum. The combination of Ø0.8 mm x 2.828 mm is the one that generates the greatest environmental impact, showing an increase of 2.47%, 0.49%, 30.62% and 50.20% for the abiotic depletion, global warming, human toxicity and acidification respectively. From the results obtained from yield stress, tensile strength and toughness, as well as the LCA of the manufacturing process, it can be stated that the novel MMC proposed in this study has a significant load capacity, both static and dynamic, capable of revaluing a metallic waste, while its manufacturing cost is reduced compared to the manufacturing cost of other MMCs.
金属基复合材料(MMC)通常是通过将增强材料分散并完全连续地嵌入到单片材料或金属基体中而制成的。增强材料可以是金属、陶瓷或有机化合物，可以提高MMC的刚度、强度、导电性、耐腐蚀性、热性能、耐磨性和疲劳寿命。它的制造需要大量的能源和原材料，因为基体材料必须在熔炉中熔化。近年来，对废物的评估，以及减少产品或工艺对环境的影响，迫使一些材料废物用于制造新的复合材料。生命周期评价(LCA)是一种用于评价能源和原材料消耗以及产品或过程的废物和排放对环境的影响的工具。这项工作提出了一个综合工作室，以确定一种新型复合材料的屈服应力，抗拉强度和韧性，以及制造过程的LCA，该复合材料由EN aw6082再生铝合金基体和双向连续纤维增强的AISI 304不锈钢组成。研究了0°取向的5种线径和线间距。分别是:Ø0.32 mm x 1.41 mm， Ø0.5 mm x 1.81 mm;Ø0.6 mm x 2.177 mm;Ø0.75 mm × 2.72 mm和Ø0.8 mm × 2.7828 mm。并与未加双向连续纤维的EN aw6082再生铝基进行了对比。与未增强铝相比，0.8 mm × 2.828 mm的线径线间距组合的抗拉强度提高了136%。此外，Ø0.32 mm x 1.41 mm和Ø0.8 mm x 2.828 mm的组合使韧性增加了25%，而Ø0.6 mm x 2.177 mm的组合使韧性增加了175%。此外，对于所研究的五种直径和线间距的MMC制造过程中的一些环境影响，与未增强铝相比几乎没有太大变化。Ø0.8 mm x 2.828 mm的组合对环境的影响最大，对非生物耗损、全球变暖、人体毒性和酸化的影响分别增加了2.47%、0.49%、30.62%和50.20%。从屈服应力、抗拉强度和韧性以及制造过程的LCA结果可以看出，本研究提出的新型MMC具有显著的静态和动态载荷能力，能够对金属废物进行重估，同时与其他MMC相比，其制造成本降低。

The IP Multimedia Subsystem (IMS) is a core element of Next Generation Networks (NGNs), which aim at offering users feature-rich and QoS-enabled high-speed multimedia services. With the widespread usage of cloud computing, network function virtualization has emerged as a way to cloudify and virtualize networking resources. However, the complexity of cloud-based virtualized networks requires accurate and efficient monitoring of resources, in order to detect problems and oversee the network's operation. Few monitoring approaches and tools have been proposed in the literature. However, none of those solutions is lightweight, resource- efficient, or tailored to the needs of complex virtualized networks. In this work, we address this limitation by proposing a sophisticated and resource-efficient monitoring approach for virtualized networks - our tool is dubbed Virtual Radar. We use the virtualized IMS as a case study for testing and demonstrating the capabilities of our system. Compared to the existing monitoring tools, Virtual Radar gives a comprehensive view of a large number of high-level and low-level networking parameters and does so while imposing minimal monitoring overhead, offering a high monitoring resolution and high scalability - thus making it a valuable tool for virtual networks' monitoring.

Deploying Machine Learning algorithms at the network edge is an ongoing research goal for both industry and academic researchers. Owing to the ubiquitous nature of Internet of Things devices and smart environments in various domains, the availability of Machine learning and deep learning capabilities on edge devices is rapidly becoming a necessity to achieve full utilization of the large amounts of data produced by these devices. However, resource constrained low-cost embedded processors like microcontrollers are typically used as the edge devices, consequently limiting their computing capabilities and memory capacity, thereby making the implementation of typical Machine Learning algorithms that are generally computationally expensive on these constrained devices extremely challenging. Therefore, in this paper we adopt a proof-of-concept approach to demonstrate the deployment procedure of an anomaly detection algorithm on low-cost and low-power embedded devices for potential application in the healthcare and wellness domain.

The purpose of this study is to explore different procedures used to develop a proposal for a sun-shading protection system employing modular elements on building facades, virtual simulations within constructed educational buildings, and a comparison of the effect of daylight impact inside the spaces using educational and free licensing applications. The case study was conducted at educational facilities at FCITEC Valle de las Palmas university campus. Conduct essential explorations within Grasshopper and the LadybugToos software using the inside interface. The effect on the facade was verified through the use of in-situ instruments and applications that enable the collection of data for analysis and decision-making applications for the indoor environment, obtaining an improvement of 95% in spaces with large format windows facing south of over 90% window to wall ratio or more, allowing the correct development of activities in interior spaces by having imperceptible glare, comfort light and visual for daily activities, in simulated spaces, reducing from ~49,000 lux to ~1,300 lux.

One third of humans' life is spent at work, therefore, the last decades have seen an increasing interest of companies in guaranteeing safety and security to employees in their plants, offices and industries. One of the paradigms that has mostly contributed to the transformation of the interest into real interventions is the Internet of Things that, thanks to its multitude of connected devices have enhanced various daily employees' routines and activities. Although different solutions have already been proposed to this aim they are usually focused on verifying the operation of the entire industrial plant without any specific attention to the respect of “micro”-measures, like the closure of a gate. In this paper we propose a modular architecture, designed within the SENERGY Project, with the aim of supporting the energizing and de-energizing of a set of industrial machines and guaranteeing, at the same time, the safety of workers in their maintenance duties. Specifically, the paper is focused on the exploitation of a remote device controllable through a 2.4 Ghz radio interface to both monitor the respect of specific safety measures and promptly intervene in case of necessity. A prototype is implemented through a commercial fast-prototyping device used to demonstrate the feasibility of the proposed solution and open up to future works.

A prototype is implemented through a commercial fast-prototyping device used to demonstrate the feasibility of the proposed solution and open up to future works.","PeriodicalId":295373,"journal":{"name":"2022 7th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126771622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maritime Shipping emissions represent the 13% of the overall EU greenhouses gas emissions (GHG) of the whole transport sector. It is estimated that they could increase between 50% and 250% by 2050 under a business-as-usual scenario, undermining the objectives of the Paris Agreement. From 2021, the European Commission adopted a series of legislative proposals to achieve climate neutrality in the EU by 2050, including the intermediate target of at least 55% net reduction in GHG emission by 2030. Despite hydrogen is worldwide considered a valid option to reach the emission reduction targets, being part of the IMO strategy also, a common approach to face the design challenges due to hydrogen introduction in waterborne transport is not yet available. Focus of this study is the adoption of hydrogen-based propulsion technologies for passenger ferries, with the aim to draft the strategies that can be adopted to reach that goal. An overview of the current state-of-the-art of hydrogen-based fuel passenger ships is presented: the EcoDesign Strategy Wheel (a tool to helps embed sustainability into any innovation and consider life-cycle impacts of the product) has been chosen to highlight the different approaches adopted by the designers of the existing vessels. The same tool has then been applied to three reference scenarios developed within the EU-funded project “e-SHyIPS” (Ecosystemic knowledge in Standards for Hydrogen Implementation on Passenger Ship). The outcome is a comparison among the two approaches highlighted during the analysis, which provides design support during the future challenges designers and shipbuilders will be called to face during the design loop phases.

This paper highlights that public lighting is a significant consumer of electricity and analyses the electricity consumption for public lighting in Croatian urban settlements. Since public lighting is a considerable consumer of electricity, it is important that it be as energy-efficient as possible. The paper points to the fact that the energy efficiency of public lighting can change in time. For this reason, a periodic energy audit of public lighting is necessary. The energy audit of public lighting must determine whether there are measures that can improve its energy efficiency. The energy efficiency of the entire public lighting system of a municipality or a city is difficult to evaluate. The paper presents two energy efficiency indicators that allow to evaluate the energy efficiency of the public lighting system of a municipality or a city. Then, using these indicators, it studies the energy efficiency of the public lighting systems of three Croatian municipalities.
