As the world’s economy is developing fast and as a result of this, the life quality of people has become better and better, so they can obtain the living materials they need. It can help people live a better life, but after the valuable parts of the living materials have been used, they will become biological waste. New methods of treating biological waste have been developed. This thesis will first introduce the situation of the global world and the treating methods. Then this thesis will discuss about the new treating methods and their advantages to the environment. The impact of biological waste on the environment can be divided into land, sea and air . The thesis will use some real examples and some figures to show the impact of biological waste on the environment. Finally the thesis will include a discussion of the sustainable development and the circular economy, which can be accepted by many countries around the world and will have a positive influence of the environment.
With the rapid development of deep learning and computer vision, related technologies and equip-ment have been widely used in various fields. And the most basic part of computer vision, as well as the most important step in image understanding, is target detection. Target detection can select the specified object in a large number of captured images. This helps researchers confirm more infor-mation about the target object, and further locate and classify the object. Based on the nature and characteristics of target detection, combined with the current situation of the epidemic, computer vision should be more applied to epidemic prevention. According to multiple studies, in addition to COVID, there are a number of seasonal diseases that can be reduced by wear-ing masks. Target detection can be used to judge the situation of people wearing masks and help the staff in public places to judge the current environment and further processing in time. At present, such tools have not been widely used in the market, so the main direction of this system is to design a practical, lightweight and universal mask recognition system. The system is designed to detect the wearing of masks in complex scenarios, which can help employees in crowded public places judge the situation of people wearing masks. he system uses Pytorch as a framework, uses YOLO V5 target detection algorithm to classify the video or image after feature extraction, which can make more accurate judgment, and uses PyQt to make a simple window that presents the results to the user.
UNESCO Global Geoparks, as approaches that are led by local communities for the conservation of heritage that is of international value, are considered to be effective tools at the local level in achieving certain of the Global Sustainable Development Goals. China has the largest number of UNESCO Global Geoparks of any country in the world. These UNESCO Global Geoparks in China have greatly contributed to the development of ge-otourism in China, however, multiple designations and overheating in pursuing tourism and economic development can result in negative impacts in the development of these UNESCO Global Geoparks. Whether the three main focuses of the UNESCO Global Ge-opark, heritage conservation, education and local economic development, as defined by UNESCO are equally concerned in the establishment and development of UNESCO Global Geoparks in China is questionable. Furthermore, this research is also devoted to understanding the relationship of the spatial distribution of UNESCO Global Geoparks in China with the relevant socio-economical situations in the areas in question. This study is conducted through the qualitative research approach with questionnaires. Two questionnaires were developed for two different target groups in order to collect data from two different perspectives. One target group is the representatives of Chinese UNESCO Global Geoparks. The other is university students of various fields in China. Both questionnaires were distributed remotely to the target groups, through a shared link to the corresponding Microsoft Forms online survey page for that questionnaire. The re-sults indicate that most people in these two groups regard geological heritage conserva-tion itself as the most important goal for Chinese UNESCO Global Geoparks. Responses in this research also suggest that the representatives of Chinese UNESCO Global Ge-oparks are more concerned with the improvement in education and raising public aware-ness, while similarly university students in China tend to believe that the largest challenge for Chinese UNESCO Global Geoparks is raising public awareness so as to minimize the negative impacts people would bring to the natural environment in the territory of these UNESCO Global Geoparks.
With the development of society, talents are more and more important to each field. The final competition of companies is the talents competition. In other words, talents become the core of organizations’ development. How to allocate HR reasonably is worth to study. However, HRM is in a developing stage in China. Most issues affect the development of HRM. Chinese state owned companies are the typical representatives for studying the development of HRM in China. Training and development is the indispensable part of HRM. This study is to use induct interview method to find out the existing issues of training and development in Chinese state owned subsidiaries. The case company LQ Coal-Fired Power Plant is a third level subsidiary of a global top 500 company that is named China Huaneng Group. By analyzing the data that is collected from the case company, the main issues of training and development in the case company are found.

Työn teettäjä oli Raahen museo. Työn tarkoituksena oli suunnitella ja toteuttaa käyttäjäliittymä järjestelmään, jolla mallinnetaan arkeologisia kaivauksia Raahen ympäristössä. Tärkein osa työstä oli suunnitella ohjelma, joka huolehtii kommunikoinnista tietokoneen ja kapasitiivisen sensorilevyn välillä. Sensorilevy koostuu 60*60 cm:n kokoisesta sensorikalvosta ja piirilevystä, jolla on sensoripari ja mikrokontrolleri Atmel’sATmega 32L. Piirilevyllä on kapasitanssin mittauspiiri (AD7147) ja sarjaportti - USB -muunnin (FT232R). Sensorilevy tunnistaa käden aseman jopa 10 cm:n etäisyydellä.Tietokoneen kommunikointiohjelma lähettää sensorilevylle jatkuvasti useita kertoja sekunnissa komennon, johon sensorilevyn mikrokontrolleri vastaa lähettämällä käden aseman koordinaatit. Käyttöliittymäohjelman tehtävänä on ohjata käyttäjälle tulevia ilmoituksia ja vaihtaa kuvia ja ääniä. Kuvien vaihto tapahtuu kun käyttäjä tekee kädellään kaivamista matkivia liikkeitä. Näin simuloidaan yhä syvemmälle etenevää arkeologista kaivausta. Työssä saatiin toteutettua toimivat kommunikointi- ja käyttöliittymäohjelmat, jotka toteutettiin C++ -kielellä. Näitä voidaan hyödyntää museon muissa vastaavissa järjestelmissä.
DM is “direct mail “, which is generally translated from English, abbreviated as DM. It means the multiform advertisements with the given information that are delivered to the target groups (potential customer, individuals and enterprises) directly by mailing service. DM is ranked a third media abroad following TV network and newspaper. It accounts for 15 - 20 % market share of the advertising market. However, in China, DM only accounts for less than 3 % market share at present, therefore, DM has quite large space to develop. There are opportunities, and also some problems to be solved.

A customer information system is a typical information management system. It involves three aspects, the backstage database establishment, the application development and the system maintenance. A car insurance information management system is based on browser/server structure. Microsoft SQL Server establishes the backstage database. Active Server Pages, from Microsoft as well is used as the interface layer. The objective of this thesis was to apply ASP to the dynamic storage of a web page and series of database applications in order to create a car insurance information management system. The backstage database structure and the interface layer connection was created by analyzing the function of the customer information system, the module division, the database pattern. The result of this thesis was a car insurance information management system in which the operators can perform customer information updating, inquiry and statistics. The system provides a simple information management method.
Orthogonal frequency division multiplexing (OFDM) is a multicarrier transmission scheme and has been widely used in communication systems due to the advantages like simpler equalization, flexible signal arrangement and so on. Also, wireless communication can provide high data speed in cellular systems, which makes internet connection via mobile and other user equipment the primary approach in daily life. The existing long term evolution (LTE) and fourth-generation (4G) systems use OFDM as a downlink scheme and provide very high peak data speed. However, the development of user equipment (UEs) operating with high data rates and the continuously growing number of users creates needs for more features and high capacities for wireless communications. For meeting the needs of the latest and future applications, fifth-generation (5G) technologies are under intensive research and development, while the first phase of 5G is actively deployed by the operators. Those technologies aim to reduce the latency, reduce power consumption, improve the throughput and support more users. In addition, the usage of 5G technologies can be categorized into three branches: enhanced mobile broadband (eMBB), ultra reliable low latency communication (URLLC) and massive machine type communication (mMTC). Because of the high spectral efficiency and other advantages of OFDM, it is still seen as a suitable modulation technique for 5G wireless communication applications. The most common OFDM scheme is CP-OFDM, which can cancel inter symbol interference (ISI) and ease the equalization process. However, the use of cyclic prefix (CP) introduces overheads which reduce the spectral efficiency and increase power consumption and latency. To meet the requirements of low latency and spectral efficiency in 5G New Radio (5G NR) applications, avoiding the usage of CP would be an interesting possibility if it could be done without severe drawbacks. This thesis provides one novel CP-free method called modified CP-free OFDM which can be used in 5G single input single output (SISO) communication. Comparing with existing CP-free designs, it does not require complex equalization algorithms or extra procedures for receivers’ detection process. Also, it can achieve similar performance with conventional CP-OFDM with minor modifications on the receiver side with respect to basic CP-OFDM receiver. In the experiment part of the thesis, the modified CP-free OFDM was tested under TDD SISO communication scenarios with line-of-sight (LOS) and non-line-of-sight (NLOS) channel models, considering both, normal and pre-equalized configurations. Simulations are used to evaluate different variants of the scheme regarding the three main performance aspects: bit-error-rate (BER), peak-to-average power ratio (PAPR), and power spectral density (PSD) of the transmitted signal.
Active Shape Model (AAM) and Active Appearance Model (AAM) are the commonly used methods in facial landmark localization, in the past 20 years, there are a few extended methods, which are based on the classical ones, being published. In this master thesis, the classical Active Shape Model (ASM) and Active Appearance Model (AAM) are well studied and summarized, especially ASM, which is also introduced in formulation. Two newly extended versions based on Active Shape Model are introduced and implemented through the thesis work. Stacked Active Shape Model (Stasm), which is much closer to the classical ASM, achieves a very good result on frontal face image landmark detection, so that it is the emphasis of this thesis. Besides we use Component based ASM as the comparison method, which is another Active Shape Model method based on component analysis. We performed these two methods for facial images from different situations: frontal and non-frontal images, single and group images. From the observation and data results, we show that Stasm still has room for improvement on facial feature localization. We explore the theoretical differences of these two extended versions and propose ideas for improvement in the later chapters.
Osteoclasts are cells responsible for bone resorption. These cells undergo extensive membrane re-organization during their polarization for bone resorption and form four distinct membrane domains, namely the ruffled border, the basolateral membrane, the sealing zone and the functional secretory domain. The endocytic/biosynthetic pathway and transcytotic route(s) are important for the resorption process, since the endocytic/biosynthetic pathway brings the specific vesicles to the ruffled border whereas the transcytotic flow is believed to transport the degraded bone matrix away from the resorption lacuna to the functional secretory domain. In the present study, we found a new transcytotic route from the functional secretory domain to the ruffled border, which may compensate membrane loss from the ruffled border during the resorption process. We also found that lipid rafts are essential for the ruffled border-targeted late endosomal pathways. A small GTP-binding protein, Rab7, has earlier been shown to regulate the late steps of the endocytic pathway. In bone-resorbing osteoclasts it is involved in the formation of the ruffled border, which displays several features of late endosomal membranes. Here we discovered a new Rab7-interacting protein, Rac1, which is another small GTP-binding protein and binds to the GTP-form of Rab7 in vitro. We demonstrated further that Rab7 colocalizes with Rac1 at the fusion zone of the ruffled border in bone-resorbing osteoclasts. In other cell types, such as fibroblast-like cells, this colocalization is mainly perinuclear. Because Rac1 is known to control the actin cytoskeleton through its effectors, we suggest that the Rab7-Rac1 interaction may mediate late endosomal transport between microtubules and microfilaments, thus enabling endosomal vesicles to switch tracks from microtubules to microfilaments before their fusion to the ruffled border. We then studied the role of Rab-Rac1 interaction in the slow recycling pathway. We revealed that Rac1 also binds directly to Rab11 and to some other but not all Rab-proteins, suggesting that Rab-Rac1 interaction could be a general regulatory mechanism to direct the intracellular vesicles from microtubule mediated transport to actin filament mediated transport and vice versa. On the basis of our results we thus propose a new hypothesis for these GTPases in the regulation of intracellular membrane flow.
