تابع هدف در تصادف خودرو، مسالة تغییر شکل سازة خودرو به شکلی کاملاً منظم و کنترل شده بدون آسیب رسیدن به فضای سرنشین می باشد. به این منظور سازة خارجی محفظة سرنشین، بایستی جهت جذب انرژی تصادف و کاهش نیروی منتقل شده به سرنشینان، دچار لهیدگی گردد. در این مقاله در فرایند طراحی ابتدا طرح بدنه منفصل خودرو در نرم افزار catia مدل سازی شده، سپس توسط نرم افزار پیش پردازش hyper mesh المان بندی شده است و در ن...
توزیع های چند متغیره، نقش مهمی در تئوری آمار وکاربردهای آن داشته است، بنابر این همواره مورد توجه محققان و دانشمندان علوم مربوطه بوده. نکته ی مهمی که بیشتر پژوهشهای محققان را به خود اختصاص داده، بدست آوردن و یا بررسی توزیع های چند متغیره بوسیله ی توزیع های حاشیه ای آنهاست. می دانیم که با داشتن توزیع مشترک، دستیابی به توزیع های حاشیه ای چندان مشکل نیست. اما در مورد ساختن توزیع مشترک و بررسی ویژگ...
advanced driver assistance systems (adas) have the potential to accomplish a major contribution to road safety. this is valid for minor crashes to very severe accidents with personal injuries. the allianz centre for technology attends the development of new driver assistance systems by carrying out accident analysis and estimating the efficiency of new adas. in this context new adas from differ...
Various organophosphorus compounds, particularly those with low acute toxicity levels, such as Fenitrothion (common name; Sumithion), Fenthion (common name; Baycid) and Pyridaphenthion (common name; Ofunack), are widely used as insecticides around the world. PAM (2-Pyridinum aldoxime methiodide), the specific antidote against Parathion, is not very effective against poisoning by these organopho...
Stock price crash risk has a significant impact on investors, creditors, managers, and shareholders, so the prediction of this phenomenon is a very important issue in investment and risk management decisions. This research investigates the effect of business strategy and stock price synchronicity on stock price crash risk. Following Bentley et al.[2], composite strategy score has been used to ...
Thin-walled structures like crash boxes may be used as energy absorption members in automotive chassis. There have been many studies addressing the behaviors of energy absorption members on frontal crash. These researches have attempted to predict the energy absorption and maximum impact load in shell structures. The energy absorption and maximum impact load depend on many parameters including ...
This study aimed at indexing crash worthiness capability of 20 most frequently used car brands in Iran. Since rollover crashes are one of the most important crash types due to their high impact on crash severity, they were chosen as the case study of the current research. In this regard, the data of 42,118 rollover crashes of urban and rural roads of Iran which occurred from 2009 to 2012 was us...
Placenta-sequestering Plasmodium falciparum involved in the pathogenesis of pregnancy-associated malaria (PAM) in otherwise clinically immune women expresses particular variant surface antigens (VSA(PAM)) on the surface of infected erythrocytes that differ from VSA found in parasitized nonpregnant individuals (non-PAM type VSA). We studied levels of immunoglobulin G (IgG) and IgG subclasses wit...
Peptidylglycine alpha-amidating monooxygenase (PAM) is an essential enzyme that catalyzes the COOH-terminal amidation of many neuroendocrine peptides. The bifunctional PAM protein contains an NH2-terminal monooxygenase (PHM) domain followed by a lyase (PAL) domain and a transmembrane domain. The cytosolic tail of PAM interacts with proteins that can affect cytoskeletal organization. A reverse t...
Group A streptococci (GAS) display receptors for the human zymogen plasminogen on the cell surface, one of which is the plasminogen-binding group A streptococcal M protein (PAM). Characterization of PAM genes from 12 GAS isolates showed significant variation within the plasminogen-binding repeat motifs (a1/a2) of this protein. To determine the impact of sequence variation on protein function, r...
