No full textPrvní část této práce se zabývá popisem současných technologií strojního spřá-dání. Jedná se o prstencové, rotorové a tryskové spřádání. Produktem spřádacích strojů je příze, čili základní materiál výroby látek. V další části je podrobně popsán současný stav uzlu manipulátoru zvedače dutinky spřádacího stroje TORNADO J20, firmy RIETER. Je popsána jeho konstrukce, kinematika, pracovní cyklus a požadavky kladené na tento manipulátor. Následují možností optimalizace, kde je popsáno více možností řešení jednotli-vých funkcí manipulátoru, na závěr je podle multikriteriální analýzy vybráno nejlepší řešení, které je zpracováno v další části. Autorem byl vytvořen 3-D model optimalizovaného zakladače dutinky. Polohovací mechanismus zachovává současnou kinematiku, je tedy velice podobný. Ale chapadlo bylo navrženo jako pasivní, díky tomu se snížilo zatížení polohovacího mechanismu. Optimalizace byla provedena především pro snížení celkových výrobních nákladů a pro snížení hmotnosti manipulátoru. V závěru práce je porovnání současného a nového řešení. Nechybí ani ekono-mické zhodnocení.The first part of this thesis describes the current technologies of mechanical spin-ning. This is a ring, rotor and air-jet spinning.

Object Knowledge and the Emergence of Language
No full textInfants' spontaneous play with objects was examined for evidence of developments in object knowledge in relation to the emergence of words and the single-word period in language development. Subjects were 7 girls and 7 boys, from different ethnic and economic backgrounds, who were studied longitudinally from 9 months to 26 months of age. Two types of displacements of objects in relation to one another were identified in the children's play: separations and constructions. The development of constructions was associated with the emergence of words, and constructions increased with age while separations decreased. The development of specific constructions, which account for knowledge of the particular properties of objects, was more strongly associated with a vocabulary spurt at the end of the single-word period than with chronological age. Despite the wide variation in the infants' ages when developments in language and play were reached, relations between achievements in the two domains were consistent among them, as confirmed with the Friedman test, p<.001. The results are discussed in terms of the cognitive developments required for play with objects and saying words
Neurosciences of infant mental health development: recent findings and implications for counseling psychology
No full textThis article is about the neural correlates of infant mental health and their correspondences to social emotional development. These correspondences are organized in terms of the definition of infant mental provided by Zero to Three (2001), centered on infants' capacities regarding the experience and expression of emotions, interpersonal relationships, and learning. We conclude with implications of these correspondences for counseling psychology-namely, working with children's caregivers to maximize children's healthy social and emotional development
Ideal Weightlifting Volume and Frequency for the Male Lifter
No full textabstract: For my Honor’s Project for Barrett the Honors College, I chose to research and develop an
application on the topic of Ideal Weightlifting Volume and Frequency for The Male Lifter. The
reason I decided to center my project around this topic is due to the plethora of information
available on this subject matter. However, I was more driven to pursue this subject matter due to
the lack of implementation and usage of all the relevant information and case studies offered to
us through the means of online journals, abstracts, reports, etc.
The application will be programmed using the software known as Android Studio. Inside
Android Studio, the programming language that will be utilized is Java. The goal for this
application is to gather information from the user, and with that information, create a conducive
weekly weightlifting regiment based on the wants and needs of the user. Furthermore, the
application will only create programs on a week to week basis, thus encouraging the user to
dabble with different preferences each week. Outputting the program on a week-to-week basis is
an integral logic of this program because it is my belief that if the user is given the privilege to
change their programming on a weekly basis this will allow for flexibility, adaptability, and the
pursuance of short-term goals, which is much more tangible in the onslaught of obtaining a goal.
When browsing through the app store or the internet, it is incredibly difficult to find online
programs that utilize research and scientific credibility. Many of these programs and trainers
offer quick results that are flashy and trendy, however lack any real qualitative reinforcement.
Thus, it is my mission, with my application, to create a program that is intuitive for the user, as
well as to provide scientific programming with proper citation of case studies and reports
conducted by educated individuals

The Semantics of Verbs and the Development of Verb Inflections in Child Language
No full textThe purpose of this study was to explore the relationship between the semantic organization of verbs used in early sentences and the emergence of the inflections of the verb auxiliary (-ing, -s, -ed, irreg). In discussions of the acquisition of grammatical morphemes by Brown (1973), de Villiers & de Villiers (1973), and others, only the syntax and semantics (along with environmental frequency) of the individual morphemes themselves have been seriously discussed as contributing to the order in which they are acquired. However, the results of the present study suggest that the semantic organization of the verb system that children learn is at least as important as the meanings of the verb inflections for determining their acquisition
Visualisation of amphetamine contamination in fingerprints using tof-sims technique
No full textTime-of-flight secondary ion mass spectrometry (TOF-SIMS) was applied to detect traces of amphetamine on fingerprints. In the present study, three different lift tapes and latent powder fingerprints were tested. The obtained results show that it is possible to identify traces of a drug as well as its distribution over the tested fingerprint after its transfer from the primary base onto an adhesive lifter (secondary base). Moreover, images obtained by the TOF-SIMS technique enable the observation of very small areas of the analysed fingerprint as well as the identification of micro-objects (residues of a contaminant) that were left on the fingerprint. The use of the black latent fingerprint powder did not interfere with the TOF-SIMS analysis, which makes it possible to effectively use this technique to study the traces of substances on the revealed fingerprints.ChemE/Advanced Soft Matte
Plankton: Reconciling Binary Code and Debug Information
No full textStatic analysis has been widely used in large-scale software defect detection. Despite recent advances, it is still not practical enough because it requires compilation interference to obtain analyzable code. Directly translating the binary code using a binary lifter mitigates this practicality problem by being non-intrusive to the building system. However, existing binary lifters cannot produce precise enough code for rigorous static analysis even in the presence of the debug information. In this paper, we propose a new binary lifter Plankton together with two new algorithms that can fill the gaps between the low- and high-level code to produce high-quality LLVM intermediate representations (IRs) from binaries with debug information, enabling full-fledged static analysis with minor precision loss. Plankton shows comparable static analysis results with traditional compilation interference solutions, producing only 17.2% differences while being much more practical, outperforming existing lifters by 76.9% on average. © 2024 Copyright is held by the owner/author(s).
