The Tennessee Department of Transportation (TDOT) recently changed the specifications for its Class D (bridge deck) portland cement concrete (PCC) thus providing a wider variety of mix designs to choose from. Specifically, they increased the maximum allowable portland cement replacement rate of Class...

You can instead rely on virtual inheritance to ensure that no concrete class can inherit from NonBase, as follows (Cline et al., 1998). class NonBase; class NonBaseFinal { private: NonBaseFinal() {} friend class NonBase; }; class NonBase :virtual public NonBaseFinal { public: … };...
To make the concept of connectors more concrete, consider the example of connecting a USB device to a USB controller. The component that contains the object for the USB controller would add a connector object with type usb-port and the direction down. The component encapsulating the USB device...

Test results indicated that abrasion resistance of concrete having cement replacement up to 35 percent was comparable to the normal concrete mix with out fly ash. Beyond 35% cement replacement, fly ash concretes exhibited slightly lower resistance to abrasion relative to non-fly ash concretes. Test...
Mike Rose writes that in the practice of surgery, “dichotomies such as concrete versus abstract and technique versus reflection break down in practice. The surgeon’s judgment is simultaneously technical and deliberative, and that mix is the source of its power.” This could be said of any ...
