The packing problem consists in finding the best arrangement of objects (many geometrical forms) in a specific space called container.This new algorithm is inspired by the observations of nanometric scale electromagnetic fields. We use the electromagnetic theory of the electric field to calculate the best position to place a circular object in a configuration of other circular objects previously packing. Also, in this new algorithm we simulate two processes called \"gravity\" and \"shaken\" that compact the distribution of the objects placed in the container and allow to minimize the unoccupied space.","PeriodicalId":169865,"journal":{"name":"2018 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123254153","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}

They induce noise, wear, and fatigue problems that prevent many machines from attaining their full potential. Dynamic balancing of mechanisms allows to limit the transmission of vibrations to the base, an advantage that could be exploited in hand tools, machinery, vehicles moving in free space and robots. This work presents a method for representing a four-bar mechanism with the use of Fully Cartesian coordinates and its equations for calculating the shaking force (ShF) and the shaking moment (ShM). Such method can be applied and it is useful for the analysis of multi-scale (meso/micro/nano) mechanisms. The projected Gradient Descent is used to minimize the ShF and ShM functions with the aim of balancing the system. The Taylor’s theorem was used for calculating the step length. The multiobjective optimization problem was solved using a linear combination of the objectives. The result of this methodology reduces successfully the ShF and the ShM by 31% and 65%, respectively.","PeriodicalId":169865,"journal":{"name":"2018 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123687460","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}

In this study, we applied a method based on nanotechnology to produce encapsulations of several flavor profiles. Facial expressions were detected through the Microsoft Kinect sensor and video images of 120 volunteers tasting five different flavor samples were obtained. A neural network was trained to measure emotions through facial expressions in every frame. Then, the combination of the consumer’s evaluations, the frame number interval where the consumers tried the sample, and the expressions found in the videos were used to solve a regression problem using different supervised learning techniques: Support Vector Machines for regression and Multilayer Perceptron and Regression Trees to predict whether a specific taste might be accepted or rejected. We show that this methodology could be used in food marketing.","PeriodicalId":169865,"journal":{"name":"2018 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124468337","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}

The static performance is discussed for CNT devices with chemical or electrostatic doping achieved by increasing the carrier concentration and by adding additional gates, respectively. The device is designed with an optimized substrate and a horse-shoe shaped coplanar access both suitable for high-frequency applications. Diode performance indicators such as rectifying factor and storage time are obtained and compared to experimental data. Based on the equivalent circuit analysis at forward bias and the Shockley diode equation, intrinsic and extrinsic cutoff frequencies for gate-less devices are obtained. Further device optimization could lead to an improved cutoff frequency as shown by assuming an improved contact transparency and multitube devices. This performance study is intended to aid the technology development of CNT-based diodes for specific applications.","PeriodicalId":169865,"journal":{"name":"2018 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115267782","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}

One of the useful parameters for design and control of this process is the growth velocity of the crystal, commonly known as the limit velocity. Above this limit, ice crystals will capture solids and separation will lose quality. Two-hybrid no invasive methods to follow the displacement of the ice front during a freeze concentration (FC) procedure has been tested.The methods included image segmentation, string matching technique and a bio-inspired optical flow algorithm to calculate the ice front velocity. A thermal camera was used in the experiments in order to validate the estimated movement of the ice by the image analysis procedures. Both methods were successful to follow the movement of the ice front, and the estimated displacement was between 4 and 12 pixels in 15 minutes.","PeriodicalId":169865,"journal":{"name":"2018 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133847719","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}

Our prototypical nanoassembly setup is composed of a Fenna-Mattews-Olson system hosting 8 Bacteriochlorophyll (BChl) a dyes, and a near-infrared emitting CdSexTe(1−x)/ZnS alloy-core/shell nanocrystal. BChl a has two wide windows of poor absorption in the green and orange-red bands, precisely where most of the sunlight energy lies. The selected QD is able to collect sunlight efficiently in a broader band and funnel its energy by a (non-radiative) Förster resonance energy transfer mechanism to the dyes embedded in the protein. By virtue of the coupling between the QD and the dyes, the nanoassembly absorption is dramatically improved in the poor absorption window of the BChl a.","PeriodicalId":169865,"journal":{"name":"2018 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126253028","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}

The electrical response of the filaments is measured at different elongations exhibiting good reproducibility and linearity.

Effective dispersion of CNTs is still a challenging aspect because of the van-der-Waals force of attraction between the CNTs, which tend to rebundle and/or reaggregate. Compared to physical dispersion techniques, such as solution mixing, sonication and mechanical stirring, chemical functionalization of carbon nanotubes that involves acid treatment and physiochemical method are promising approaches, which enhances the dispersion quality as well as stability. This paper presents a brief analysis of the influence of functionalization of CNT on dispersion quality and stability. Solvents such as isopropanol and ethylacetate have been used as dispersion media and the dispersions have been characterized by UV-VIS spectroscopy analysis. The investigation results shows that, physiochemical method exhibits better dispersion quality and stability compared to that of acid treatment method.","PeriodicalId":169865,"journal":{"name":"2018 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126429022","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}

It is important to assure that injured people receive assistance as quick as possible. Fall detection systems have gain more relevance nowadays. As more databases and fall detection systems are developed, there is more need to identify the challenges encountered in building and creating them. This paper addresses pre-processing, inconsistency and synchronization challenges that occur when creating a multimodal database for fall detection. We present different algorithms used to tackle these issues. We describe the issues and the corresponding solutions in order to document the lessons learned that could help others in data acquisition for multimodal databases. Applying the solutions to the issues found so far, we acquired an organized multimodal database for fall detection with 17 subjects. Furthermore, these lessons learned can be applied for data nanosensors acquisition and storage.","PeriodicalId":169865,"journal":{"name":"2018 Nanotechnology for Instrumentation and Measurement (NANOfIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129328789","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}
